What is error detection in English language learning?

Error detection in English language learning involves identifying and correcting mistakes in language use. 
This process is crucial for developing proficiency, as it helps learners understand the rules of grammar, vocabulary, and syntax more clearly. 

For instance, if a learner writes

 "She go to the store yesterday,"

 An error detection exercise would highlight the incorrect verb form "go," prompting the learner to replace it with the correct past tense form "went."

 Another example might be identifying a subject-verb agreement error, such as

 "The team are winning" 
        instead of 
   "The team is winning." 

By practicing error detection, learners can improve their language skills more effectively, as it encourages active engagement with the rules and patterns of English.

Error Detection is one of the highest-scoring topics in the English section of SSC CGL and other competitive examinations.

 Strategy for SSC CGL English (Error Detection)

Preparing for the SSC CGL English section, particularly the error detection part, requires a strategic approach to improve accuracy and speed. Here are some tips to help you excel in this area:

1. Understand Grammar Rules: 

Make sure you have a strong grasp of fundamental grammar rules, including subject-verb agreement, tense consistency, pronoun usage, and article placement. This foundation will help you quickly identify errors.

2. Practice Regularly: 

Regular practice with previous years’ papers and mock tests will familiarize you with common error patterns. This repetition will enhance your ability to spot mistakes quickly.

3. Read Carefully: 

Pay close attention to each sentence. Sometimes, errors can be subtle and require careful reading to detect discrepancies in grammar or syntax.

4. Break Down the Sentence: 

Analyze the sentence by breaking it into smaller components (subject, verb, object). This can make it easier to spot which part of the sentence contains an error.

5. Look for Common Error Types: 

Focus on frequently tested areas such as modifiers, parallelism, and idiomatic expressions. Knowing these can help you quickly identify potential errors.

6. Time Management: 

While accuracy is crucial, efficient time management is equally important. Practice under timed conditions to ensure you can complete this section within the allotted time.

7. Review and Analyze: 

After each practice session, review your mistakes to understand why you made them. This will help you avoid similar errors in the future.

By consistently applying these strategies and honing your grammar skills, you can improve your performance in the error detection section of the SSC CGL English exam.

Don't Let These Common Mistakes Hold You Back

In the above image Two aspirants, Priya and Tina, sat in a quiet corner of the library, surrounded by stacks of study materials for the SSC CGL exam. As they delved into the topic of Error Detection, Priya sighed and confessed, “I am weak in English, and it worries me when it comes to spotting errors.” Tina, always eager to help, gently corrected her, “Don't say ‘weak in English’. It's more appropriate to say ‘weak at English.’ But don’t worry, Priya, we can work on this together.” He continued, explaining that mastering error detection requires a solid understanding of grammar rules and consistent practice. “Let’s start by reviewing the common types of errors that appear in exams, like subject-verb agreement and incorrect usage of tenses,” Tina suggested, pulling out a well-worn grammar book. Priya nodded, feeling a bit more confident with Tina’s support and guidance as they embarked on their study session.

Subject - Verb Agreement (Error Spotting)

Don't skip this!

SSC repeats previous year questions -
But not always word for word.

SSC frequently ask MCQ questions related to "Concord Error"

Subject-verb agreement is a fundamental aspect of English grammar that ensures the subject and verb 
in a sentence match in number. This means that a singular subject takes a singular verb, and a plural subject takes a plural verb. Errors in subject-verb agreement can lead to confusion and misunderstandings. Here are some examples of errors and their corrections:

1. Incorrect: The list of items are on the desk.❌

 Correct: The list of items is on the desk.✔️

 Explanation: The subject "list" is singular, so it requires the singular verb "is."

2. Incorrect: Each of the boys were given a medal.❌

Correct: Each of the boys was given a medal.✔️

Explanation: "Each" is singular, so it requires the singular verb "was."

3. Incorrect : Neither the teacher nor the students has the answer.❌

Correct: Neither the teacher nor the students have the answer.✔️

Explanation: When subjects are joined by "neither...nor," the verb agrees with the subject closer to the verb, which is "students," a plural noun.

4. Incorrect: The dog and the cat is playing in the yard.❌

 Correct: The dog and the cat are playing in the yard.✔️

 Explanation: When two subjects are joined by "and," they typically take a plural verb, "are."

5. Incorrect: The team are winning their games.❌

 Correct: The team is winning its games.✔️

 Explanation: "Team" is a collective noun that is treated as singular in American English, so it takes the singular verb "is."

Understanding subject-verb agreement enhances the clarity and precision of writing, making it an essential skill for effective communication.

Basic Agreement : (Singular/Plural)

Subject-verb agreement is a fundamental aspect of English grammar, focusing on ensuring that the subject and verb of a sentence align in number, meaning they both need to be singular 
or both plural. Errors in agreement often occur when the subject and verb are mismatched. 

Here are some examples, along with corrections:

1. Incorrect: The list of items are on the desk.  ❌

   Correct: The list of items is on the desk.  ✔️

   Explanation: The subject "list" is singular, so the verb should also be singular ("is").

2. Incorrect: My friends likes to play soccer.  ❌

 Correct: My friends like to play soccer.✔️  

  Explanation: The subject "friends" is plural, so it requires the plural form of the verb ("like").

3. Incorrect: Each of the students have a schedule.  ❌

  Correct: Each of the students has a schedule.  ✔️
  
 Explanation: The word "each" is singular, so it should be followed by a singular verb ("has").

4. Incorrect: Neither the teacher nor the students was ready for the exam.  ❌

  Correct: Neither the teacher nor the students were ready for the exam.  ✔️

   Explanation: When subjects are joined by "neither/nor," the verb agrees with the subject closer to it, which is "students" in this case, requiring "were."

5. Incorrect: The team are winning the match.  ❌
 
Correct: The team is winning the match.✔️
 
  Explanation: "Team" is a collective noun and is treated as singular, thus it takes the singular verb "is."

Correct subject-verb agreement ensures clarity and precision in communication, making your writing more professional and easier to understand.

Collective Nouns 

Here are some examples of collective nouns used in error detection:

A team of programmers: 

Often, a group of software developers work together to identify and fix bugs within a software application.
  
A squad of testers: 

A dedicated group of quality assurance testers who systematically go through the software to ensure it functions correctly.
  
A panel of experts:

 When complex errors are detected, a panel of experts may be convened to provide insights and solutions based on their specialized knowledge.
  
A batch of reports: 

This refers to a collection of error logs or reports generated by a system to help identify and analyze issues.
  
A cluster of anomalies: 

In data analysis, a cluster of anomalies might indicate irregular patterns or errors that need addressing.
  
A suite of tools: 

A comprehensive set of software applications used for detecting and resolving errors in complex systems.

These collective nouns help describe various groups and sets that play a role in the process of error detection and resolution.

Here are examples of compound sentences with potential errors, along with explanations for each:

1. Incorrect: "I wanted to go for a run, but it was raining, so I stayed home."❌

  Explanation : This sentence is not incorrect, but it might be overly complex with multiple conjunctions. It's essential to ensure clarity when using multiple conjunctions.

 Correct: "I wanted to go for a run, but it was raining. Therefore, I stayed home."✔️

2. Incorrect: "She enjoys reading and she likes to write stories."❌

   Explanation : The sentence lacks a comma before the conjunction "and," which is necessary when joining two independent clauses.

  Correct: "She enjoys reading, and she likes to write stories."✔️

3. Incorrect: "The sun was shining but the air was cold."❌

   Explanation : A comma is needed before "but" as it joins two independent clauses.

   Correct: "The sun was shining, but the air was cold."✔️

4. Incorrect: "We can go to the park, or we can stay at home."❌

   Explanation : This sentence is correct with the comma before "or," but make sure it's consistently applied in similar structures.

Correct: "We can go to the park, or we can stay at home."✔️

5. Incorrect: "I was hungry so I made a sandwich."❌

   Explanation: A comma is needed before "so" to separate the independent clauses.
   Correct: "I was hungry, so I made a sandwich."✔️

These examples illustrate the importance of using commas correctly in compound sentences to ensure clarity and proper sentence structure.


Detecting errors related to indefinite pronouns can be essential for maintaining grammatical accuracy. Here are some common issues and examples:

1. Agreement with Singular Verbs: 

   Incorrect: "Everybody have their own opinions."❌

    Correct: "Everybody has their own opinions."✔️
   
Explanation: Indefinite pronouns like "everybody" are singular and should be paired with singular verbs.


   Incorrect: "Someone left their book on the table."❌

    Correct: "Someone left his or her book on the table."✔️

 Explanation: Use "his or her" instead of "their" when referring back to singular indefinite pronouns like "someone."

3. Consistency in Number:

   Incorrect: "Many of the team is going to the match."❌

  Correct: "Many of the team are going to the match."✔️
 
 Explanation: "Many" refers to a plural noun, so it should be followed by a plural verb.

4. Use with Countable vs. Uncountable Nouns:

   Incorrect: "Much of the apples were eaten."❌

Correct: "Many of the apples were eaten."✔️

Explanation: "Many" is used with countable nouns, while "much" is
 used with uncountable nouns.

5. Double Negatives:

   Incorrect: "I don’t need no help."❌

 Correct: "I don’t need any help."✔️

  Explanation: Using "any" instead of "no" avoids the double negative, making the sentence grammatically correct.

Understanding these common errors can help you use indefinite pronouns correctly in writing.

Here are some common tense errors in writing, along with examples:

1. Inconsistent Tense Usage:

   Incorrect: "She went to the store and buys some milk."❌

  Explanation: Maintain the same tense throughout the sentence unless there's a reason to change it.

2. Incorrect Future Tense:

 Incorrect: "I will see him yesterday."❌

 Correct: "I saw him yesterday."✔️

 Explanation: Use past tense for actions completed in the past.

3. Incorrect Past Tense:

 Incorrect: "He was knowing the answer."❌

 Correct: "He knew the answer."✔️

 Explanation: Use simple past for actions completed in the past, especially for stative verbs like "know."

4. Misuse of Present Perfect Tense:

   Incorrect: "I have went to the museum last week."❌

   Correct: "I went to the museum last week."✔️

  Explanation: Use simple past for actions that happened at a specific time in the past.

5. Present Tense for Past Events:

  Incorrect: "She works at the company for five years before she moved."❌

  Correct: "She worked at the company for five years before she moved."✔️

   Explanation: Use past tense for actions completed before another past event.

By being aware of these common errors, writers can improve the clarity and consistency of their work.

Here are some examples of error detection using simple tense in sentences:

Incorrect: We goes to the park on Sundays.❌

Correct: We go to the park on Sundays.✔️

 Explanation: The verb should remain as “go” to match the plural subject “we.”

Continuous Tenses 

Continuous tense can be an essential aspect of error detection in writing. 
Here are some examples:

1. Subject-Verb Agreement: 

  Incorrect: "She are running fast."❌

  Correct: "She is running fast."✔️

 Explanation: The verb "are" does not agree with the singular subject "she."

2. Incorrect Tense Usage: 

   Incorrect: "He was walking to school every day."❌

   Correct: "He is walking to school every day."✔️

  Explanation: "Was walking" suggests past action, while the context implies a habitual present action.

3. Incomplete Action: 

   Incorrect: "They eating dinner when the phone rang."❌

  Correct: "They were eating dinner when the phone rang."✔️

Explanation: The past continuous tense "were eating" correctly conveys an ongoing action in the past.

  Incorrect: "I am driving yesterday."❌

  Correct: "I was driving yesterday."✔️

  Explanation: "Yesterday" requires past continuous tense "was driving."

5. Consistency in Narrative:

Correction: "While she was cooking, her friends were arriving."✔️

Explanation: Maintaining consistency in tense enhances clarity and coherence in narrative.

These examples highlight common errors and corrections involving continuous tense, illustrating the importance of context and consistency in tense usage.

Perfect Tenses 

Perfect tenses are used to indicate completed actions in relation to another point in time. Here are some examples of error detection involving perfect tenses:

1. Present Perfect Tense:

 Incorrect: She has went to the store.❌

 Correct: She has gone to the store.✔️

  Explanation: "Gone" is the past participle of "go," which is required 
for the present perfect tense.

2. Past Perfect Tense:

Incorrect: By the time he arrived, they had already ate dinner.❌

Correct: By the time he arrived, they 
had already eaten dinner.✔️

 Explanation: "Eaten" is the past participle of "eat," which is used 
with "had" for the past perfect tense.

3. Future Perfect Tense:

Incorrect: By next year, I will have wrote three novels.❌
Correct: By next year, I will have written three novels.✔️

Explanation: "Written" is the past participle of "write," needed for the future perfect tense.

In each case, the error involves using the wrong form of the verb, typically the past simple instead 
of the past participle, which is necessary for forming perfect tenses.

Tense Consistency 

 Here are some examples of tense consistency in error detection:

Incorrect: She "wakes" up early every morning and "went" for a run.❌

Correct: She "wakes" up early every morning and *goes* for a run.✔️

Explanation: The incorrect sentence mixes present tense (“wakes”) with past tense (“went”), disrupting tense consistency. 

Incorrect: Yesterday, he "buys" a new car and "drove" it home.❌

Correct: Yesterday, he "bought" a new car and "drove" it home.✔️

 Explanation: The sentence should maintain past tense (“bought” and “drove”) because it refers to an event that happened in the past.

Correct: They "were planning" to go hiking, but the weather "was" bad.✔️

Explanation: The sentence describes past intentions and conditions, so past tense should be used throughout. 

Ensuring tense consistency helps maintain clarity and coherence in writing by aligning the verb tenses within the same time frame.

Pronoun Errors 

Here are some examples of pronoun errors in error detection:

1. Subject-Verb Agreement: 

Incorrect: "Everyone should bring their own lunch." ❌

Correct: "Everyone should bring his or her own lunch."✔️

Explanation: Since "everyone" is singular, the pronoun should also be singular.

2. Pronoun-Antecedent Agreement:

These examples highlight common errors and corrections that improve clarity and grammatical correctness in writing.

Pronoun Antecedent Agreement 

Pronoun-antecedent agreement errors occur when a pronoun does not match its antecedent in number, gender, or person. Here are some examples and explanations:

1. Singular vs. Plural
 
Incorrect: "Each of the students must submit their assignment by Friday."❌

Correct: "Each of the students must submit his or her assignment by Friday."✔️

Explanation: "Each" is singular, so the pronoun should also be singular ("his or her").

2. Gender Agreement

Incorrect: "Every nurse should ensure he records patient information accurately."❌

Correct: "Every nurse should ensure they record patient information accurately."✔️

Explanation: "Every nurse" is gender-neutral, so using "they" accommodates all genders.

3. Collective Nouns

Correct: "The team won its game, and it celebrated afterwards."✔️

Explanation: "Team" is a collective noun typically treated as singular unless emphasizing individuals.

4. Indefinite Pronouns

 Incorrect: "Someone left their umbrella in the office."❌

 Correct: "Someone left his or her umbrella in the office."✔️

Explanation: "Someone" is singular, so the pronoun should be "his or her." However, "their" is increasingly accepted in informal contexts.

5. Ambiguous Antecedent

Incorrect: "When Jessica met Sarah, she was very excited."❌

Correct: "When Jessica met Sarah, Jessica was very excited."✔️

Explanation: It's unclear who "she" refers to, so repeating the name clarifies the antecedent.

Ensuring pronoun-antecedent agreement not only improves clarity but also enhances the overall coherence of your writing.

Pronoun case (subjective - objective)

Here are some examples of pronoun case errors and their corrections:

1. Subjective Case Error

Incorrect: Me and my friend went to the store.❌

Correct: My friend and I went to the store.✔️

2. Objective Case Error:

Incorrect: The teacher gave he and I some advice.❌

 Correct: The teacher gave him and me some advice.✔️

Explanation: When the pronoun is part of the object of a verb or preposition, use the objective case "him" and "me" instead of "he" and "I."

3. Compound Subject Error

Correct: She and her brother are coming to dinner.✔️

Explanation: Use the subjective case "she" when the pronoun is part of a compound subject.

  Correct: She is taller than I (am).✔️

Explanation: When a comparison is implied, the subjective case "I" is often used if the verb is omitted but understood.

These examples illustrate common errors and corrections in pronoun cases, helping to ensure proper grammar usage.

Vague Pronoun Reference 

Vague pronoun references can lead to confusion in writing because the pronoun used does not clearly refer to a specific noun. Here are some examples and explanations:

Example :

 "When Sarah talked to Emily, she was very excited."  ❌

  Explanation : It's unclear whether "she" refers to Sarah or Emily.  

Clarify by rephrasing: 

Correct: "When Sarah talked to Emily, Sarah was very excited."✔️

Example: 

"The cake was delicious, and it melted in your mouth."  ❌

 Explanation: The pronoun "it" is vague because it's unclear if it refers to the cake or something else.  

  Specify the noun:

 "The cake was delicious and melted in your mouth."✔️

Example:

 "John gave his brother a book, but he didn't like it."  ❌

 Explanation: It's ambiguous whether "he" refers to John or his brother, and whether "it" refers
 to the book or something else.  

 Correct: Specify the subject: "John gave his brother a book, but his brother didn't like it."✔️

Example : 

"The team lost the game, which upset the fans."  ❌

 Explanation: "Which" is vague because it could refer to the team losing or the game itself.  

 Clarify the cause: 

"The team's loss in the game upset the fans."✔️

By ensuring each pronoun clearly refers to a specific antecedent, writing can become much clearer and more precise.

Modifier & Structure Error 

 Here are some examples of modifier and structure errors commonly found in writing:


This occurs when a modifier is not clearly or logically connected to the word it is supposed to modify.

Incorrect: "Walking down the street, the flowers were beautiful."❌

Correct: "Walking down the street, I found the flowers beautiful."✔️


This happens when a modifier is placed too far from the word it modifies, leading to confusion.

Incorrect: "She almost drove her kids to school every day."❌

 Correct: "She drove her kids to school almost every day."✔️

3. Squinting Modifier:

 A modifier that is placed between two words it could modify, making the sentence ambiguous.
 
Incorrect: "Students who study rarely get bad grades."❌

 Correct: "Students who rarely study get bad grades."✔️


 Occurs when elements in a sentence do not follow the same grammatical structure.

   Incorrect: "She likes reading, to swim, and biking."❌

   Correct: "She likes reading, swimming, and biking."✔️

5. Sentence Fragment: 

A group of words that does not form a complete sentence because it lacks a main clause.

 Incorrect: "Because I was hungry."❌

 Correct: "I went to the kitchen because I was hungry."✔️

6. Run-on Sentence: Two or more independent clauses are joined without proper punctuation or conjunction.

   Incorrect: "I love to write it is my passion."❌

    Correct: "I love to write; it is my passion."✔️

These examples demonstrate various modifier and structure errors that writers should watch for to ensure clarity and precision in their writing.

Misplaced Modifiers

Misplaced modifiers can lead to confusion in sentences by altering the intended meaning.
Here are a few examples:

1. Incorrect: “Running quickly, the finish line seemed to appear out of nowhere.”❌

Correct: “Running quickly, she noticed the finish line seemed to appear out of nowhere.”✔️

Explanation: The modifier “Running quickly” should clearly refer
 to the person, not the finish line.

2. Incorrect: “She served sandwiches to the children on paper plates.”❌

Correct: “She served sandwiches on paper plates to the children.”✔️

Explanation: The original sentence suggests the children are on paper plates, rather than the
 sandwiches.

3. Incorrect: “Covered in wildflowers, she admired the meadow.” ❌

Correct: “She admired the meadow covered in wildflowers.” ✔

Explanation: The misplaced modifier makes it sound as though she is covered in wildflowers.

4. Incorrect: “After roasting for several hours, I finally took the turkey out of the oven.”❌
 
 Correct: “After the turkey had roasted for several hours, I finally took it out of the oven.”✔️

 Explanation: The original suggests that “I” have been roasting for several hours.

5. Incorrect: “The man was stopped for speeding in the blue sweater.”❌

   Correct: “The man in the blue sweater was stopped for speeding.”✔️

   Explanation: The initial sentence implies that the speeding was happening in the sweater, rather than the man wearing it.

By ensuring modifiers are placed correctly, sentences become clearer and convey the intended meaning more effectively.

Dangling Modifier 

 Dangling modifiers can lead to confusing or humorous sentences because they are word groups
 that are not clearly and logically related to the words they modify.

 Here are some examples of dangling modifiers:

1. Incorrect: "Walking through the park, the flowers were in full bloom."❌

Explanation: The modifier "Walking through the park" seems to describe 
"the flowers," which is illogical because flowers don't walk.

Correct: "Walking through the park, I noticed the flowers were in full bloom."✔️

2. Incorrect: "After reading the book, the movie was disappointing."❌

Explanation: The modifier "After reading the book" appears to describe "the movie," which is not logical.

Correct: "After reading the book, I found the movie disappointing."✔️

3. Incorrect: "Hoping to win the contest, the essay was submitted late."❌
 
Explanation: The modifier "Hoping to win the contest" incorrectly modifies "the essay."

Correct: "Hoping to win the contest, she submitted the essay late."✔️

4. Incorrect: "To improve his grades, extra tutoring sessions were attended."❌

Explanation: "To improve his grades" seems to modify "extra tutoring sessions," which cannot improve 
grades on their own.

Correct: "To improve his grades, he attended extra tutoring sessions."✔️

These examples highlight the importance of ensuring that modifiers clearly and logically refer to the intended subject in a sentence.

Parallelism 

 Parallelism is a literary and rhetorical device that involves using elements in sentences that are grammatically similar or identical in structure, sound, meaning, or meter. Here are some examples:

Lists and Series: 

"She enjoys reading, cooking, and hiking."

Explanation: Each verb form is in the present participle form, maintaining consistency.

Comparative Structures: 

"He is not only a talented musician but also an accomplished writer."

Explanation: The phrases "not only" and "but also" introduce parallel elements.

Correlative Conjunctions: 

"Either you start studying now, or you risk failing the exam." 

Explanation: The structure after "either" and "or" is parallel.

Balanced Sentences:

 "To err is human, to forgive divine." 

Explanation: The infinitive structure is repeated in both parts of the sentence.

Repetition for Effect: 

"We shall fight on the beaches, we shall fight on the landing grounds, we shall fight in the fields." 

Explanation: The repetition of "we shall fight" emphasizes determination.

Parallelism enhances readability and rhythm in writing, making ideas more memorable and persuasive.

Common Questions About Error Detection & Correction in English Answered

 How do I know whether to use "Angry with ", "At" or "On"?

Choosing the correct preposition to use with "angry" depends on the context and what you are specifically trying to convey.

1. Angry with: This is typically used when referring to being upset with a person or group of people. 

For example, 

"She was angry with her friend for canceling their plans at the last minute."

2. Angry at: This is often used similarly
 to "angry with," but it can also refer to inanimate objects or situations.

 For example, 

"He was angry at the computer for crashing during his presentation," 

or 

"She was angry at him for not listening."

3. Angry on: This is less common and is usually used in the context of being angry on behalf of someone else, i.e., when you are upset due to an injustice or mistreatment that affects another person.
 
For example,

 "He was angry on behalf of his sister, who was unfairly criticized."

Understanding these subtle differences can help you choose the appropriate preposition based on the nuance you wish to convey in your sentence.

What are the most common subject- verb agreement errors in SSC exams?

Subject-verb agreement errors are common in SSC exams, often arising from misunderstanding the rules that govern how subjects and verbs must match in number. One frequent error occurs with collective nouns. 
For example, 

"The team is playing well" is correct.

But some might mistakenly say:

"The team are playing well" if they treat the team as individuals rather than a single entity.

Another common error involves sentences where the subject is separated from the verb by a phrase or clause. Consider the sentence 
"The bouquet of roses smells wonderful."

 Some might incorrectly match the verb to the nearest noun and say:

"The bouquet of roses smell wonderful."

Errors also arise with indefinite pronouns. 

For instance, 

"Everyone has their own opinion" 
is incorrect in formal English; it should be "Everyone has his or her own opinion," as "everyone" is singular.

Additionally, errors can occur with compound subjects. When two singular nouns are joined by "and," the verb should be plural: 

"The cat and the dog are playing."

 However, if the nouns are joined by "or" or "nor," the verb should agree with the nearest subject: "Neither the cat nor the dogs are hungry."

Awareness of these common pitfalls can help students avoid subject-verb agreement errors in their exams.

What are the tips to boost accuracy and speed in error detection questions?

Boosting accuracy and speed in error detection questions requires a combination of practice, strategic reading, and familiarity with common error patterns. Here are some tips to enhance your skills:

1. Understand Grammar Rules: 

A strong grasp of grammar rules is essential. Familiarize yourself with common grammatical errors such as subject-verb agreement, tense consistency, pronoun usage, and parallelism.

2. Read Carefully: 

Approach each sentence with a critical eye. Read slowly to catch subtle errors that might be missed when reading quickly.

3. Identify Common Errors: 

Certain errors occur frequently. Look out for misplaced modifiers, incorrect verb forms, punctuation mistakes, and incorrect word usage.

4. Practice Regularly: 

Regular practice with error detection exercises will improve both your speed and accuracy. Use practice tests and quizzes to hone your skills.

5. Use Elimination Techniques: 

If you're unsure about an error, try eliminating options that are clearly correct to narrow down the possibilities.

6. Break Down Sentences: 

Analyze complex sentences by breaking them into smaller parts. This makes it easier to spot errors.

7. Read Aloud: 

Sometimes, reading a sentence aloud can help you catch errors that you might not notice when reading silently.

Example:

Incorrect: "Each of the students have their own locker."

Correct: "Each of the students has their own locker."

In this example, the error is in subject-verb agreement. "Each" is singular, so the correct verb
 form is "has" instead of "have." 

By integrating these strategies into your study routine, you can enhance your ability to quickly and accurately detect errors in any text.

Why error detection and correction skills are important for exam success?

Error detection and correction skills are vital for exam success because they enhance a student's ability to identify and rectify mistakes, which can significantly influence their final scores. 
For instance, 

in a math exam, being adept at spotting calculation errors can prevent the loss of crucial points. 

Similarly, in essay-based exams, recognizing grammatical or spelling errors can improve the clarity and professionalism of one's writing, potentially leading to higher marks.

 Additionally, these skills foster a deeper understanding of the subject matter, as students learn to critically evaluate their work and refine their knowledge through the correction process. 

This not only boosts immediate exam performance but also strengthens long-term academic proficiency. 

Moreover, practicing error detection and correction can build confidence, as students become more aware of their common mistakes and learn strategies to avoid them, leading to a more polished and accurate exam submission.

10 Common Mistakes in English for SSC CGL, CHSL & Other Government Exams 

     Study Smarter, Not Harder!

How to Avoid Common Mistakes in SSC CGL:

Basic 10 Common English Mistakes in SSC CGL

The Staff Selection Commission Combined Graduate Level (SSC CGL) exam is a competitive test in India where proficiency in English grammar is crucial. 

Here are ten common English grammar mistakes that candidates often make:

1.Subject-Verb Agreement: Many learners struggle with ensuring that the subject and verb in a sentence agree in number and person. 

For example, 
He go to the market. ❌
He goes to the market.✔️

2. Tense Confusion: Mistakes in tense usage, such as mixing past and present, can lead to confusion. 

For instance, 
I am going to the store yesterday ❌
I went to the store yesterday.✔️

"a," "an," and "the" is frequent. Remember that "a" and "an" are for non-specific items, while "the" is for specific ones. 

For example,
  •  "an university" ❌
  •   "a university." ✔️
  • Next year, she will get admission to a university.✔️
  • Next year, she will be admitted to a university.✔️
Rule: Use a/an according to the sound, not merely the first letter.
  • a university → /juː/ sound
  • a European country → /juː/ sound
  • an umbrella → vowel sound
  • an honest person → silent h, so vowel sound
4. Wrong Prepositions: Using incorrect prepositions can change the meaning of a sentence. 

For example, 
  • "I am good in English". ❌ 
  • "I am good at English."✔️
5. Pronoun Reference Errors: Ensuring pronouns clearly refer to the correct noun is essential. 

For example, 

When John met Tim, he was late. Specify who "he" refers to.

6. Misplaced Modifiers: Modifiers should be placed close to the word they modify to avoid confusion. 

"She almost drove her kids to school every day" implies she didn’t complete the action, while "She drove her kids to school almost every day" is clearer.

7. Confusion Between Adjectives and Adverbs: Mixing up forms like "quick" (adjective) and "quickly" (adverb) is common. 

For example, 
  • She runs quick. ❌
  • She runs quickly. ✔️
8. Double Negatives: Using double negatives can reverse the intended meaning. 
  •  I don’t know nothing.❌
  •  I don’t know anything.✔️
9. Overuse of Passive Voice: While not technically incorrect, overusing the passive voice can make sentences less direct. 

For instance, 

"The ball was thrown by John" is less direct than "John threw the ball."

10. Incorrect Word Order in Questions: Mistakes in word order are common in questions. 
  • You are coming with us?" ❌
  • Are you coming with us?"✔️
Being aware of these common errors can help candidates prepare more effectively for the SSC CGL and improve their overall English proficiency.

10 Grammar Mistakes Candidates Should Avoid 

Here are 10 common grammar mistakes that competitive exam aspirants frequently make, along with the rules and corrections to master them:

Subject Verb Agreement with Quantifiers:

Mistake: One of my friend is participating in the quiz.❌

Correction: One of my friends is participating in the quiz.✔️

Rule: The phrase "One of the" is always followed by a plural noun and a singular verb (e.g., One of the (plural noun) is (singular verb).

Misusing "Between" vs. "Among"

Mistake: Distribute the study material between all five students.❌

Correction: Distribute the study material among all five students.✔️

Rule: Between when referring to two distinct items or people (or specific individual items regardless of number). Use among when referring to three or more items or members of a group.


Mistake: Walking down the hall, the book was dropped.❌

Correction: Walking down the hall, he dropped the book.✔️

Rule: A modifying phrase at the beginning of a sentence must clearly 
and logically describe the subject that immediately follows the comma. (A book cannot walk down the hall.)

Confusing "less" and "fewer'

Mistake: There are less questions left to attempt.❌

Correction: There are fewer questions left to attempt.✔️

Rule: Use fewer for countable nouns (questions, books, mistakes) and less for uncountable nouns or quantities (time, money, water, effort).

Incorrect use of "Neither....Nor"/ "Either....or"

Mistake: Neither the instructor nor the students was present.❌

Correction: Neither the instructor nor students were present.✔️

Rule: When two subjects are connected by neither ....nor or either.... or, the verb must agree with the subject closest to it (the students is plural, so use were).

Misplacing " Hardly", "Scarcely", and "No Sooner"

Mistake: Hardly I had entered the room when the exam started.❌

Correction: Hardly had I entered the room when the exam started.(or No sooner had I entered.... than.....)✔️

Rule: When sentences begin with negative adverbs like Hardly, Scarcely,
 or No sooner, inversion occurs - the auxiliary verb comes before the subject. Also, pair Hardly/ Scarcely with when, and No sooner with than.

Prepositions After Words

Mistake: He is senior than me by two years.❌

 Correction: He is senior to me by two years.✔️

Rule: Comparative adjectives ending in -ior ( senior, junior, superior, inferior, prior) take the preposition to, not than.

Using "Although" or "Though" with "But"

Mistake: Although he worked hard, but he failed the test.❌

Correction: Although he worked hard, he failed the test. (or Although he worked hard, yet he failed....)✔️

Rule: Although and but are both conjunctions expressing contrast. Using both in the same clause creates redundancy. Pair although with a comma or yet, never but.

Incorrect Pronoun Case After Prepositions 

Mistake: This matter is strictly between you and I.❌

Correction: This matter is strictly between you and me.✔️

Rule: Prepositions(between, except,
like, besides, for) must be followed by objective pronouns (me, him,her, us, them), not subjective pronouns( I, he, she, we, they).

The Unnecessary "Return Back"/ "Repeat Again"

Mistakes: 
  • Please repeat the question again.❌
  • He returned back to his hometown.❌
Corrections: 
  • Please repeat the question.✔️
  • He returned to his hometown.✔️
Rule: Avoid redundancy. Words like repeat, return, revert, reply, re-examine already contain the concept of "again" or "back".

Subject Verb Agreement is one of the most heavily tested topics in competitive exams ( such as SSC, Banking, NDA, CDS). 

The basic principle is simple: A singular subject takes a singular verb, and a plural subject takes a plural verb. However, exams target edge cases, tricky structures, and confusing noun phrases.

Here is a comprehensive breakdown of the major Subject Verb Agreement rules, along with common exam traps.

The Proximity Rule (Either .....or, Neither....ñor)

When subjects are connected by either...or, neither ... nor, not only .... but also, or the verb agrees with the subject closest to it.

Incorrect: Neither the teacher nor the students was present in the auditorium.❌

Correct: Neither the teacher nor the students were present in the auditorium.✔️

Correct: Either the students or the teacher was late. (teacher is closest to the verb).✔️

💡Exam Tip: Look at the noun directly preceding the verb slot to determine the verb's number.

Parenthetical Expressions & Additive Phrases 

When a singular subject is followed by phrases such as along with, together with, as well as, in addition to, accompanied by, with, or besides, the verb remains singular. These phrases do not make the subject plural.

Incorrect: The captain, along with his team members, were awarded medals.❌

Correct: The captain, along with his team members, was awarded medals.✔️
(the core subject is "Captain", which is singular)

"One of the" vs. "The only one of the"

This is a high frequency exam concept involving relative pronouns (who, which, that).

Pattern A (One of + Plural Noun + Relative Pronoun + Plural Verb) :

Example: He is one of those officers who have served with distinction.

Reason: Who refers back to officers (plural), so the relative clause takes a plural verb.

Pattern B (The only one of + Plural Noun + Relative Pronoun + Singular Verb)

Example: He is the only one of those officers who has served with distinction.

Reason: The only one restricts the subject do a single individual.

Collective Nouns ( Unity vs. Division)

Collective nouns (such as jury, committee, team, audience, class, government) take us singular verb when acting as a unified body, but a plural verb when members Act individually or are divided.
  • Action: Unified action
  • Example: The committee has submitted its report.
  • Verb Type: Singular
  • Action: Divided action
  • Example: The committee are divided in their opinions.
  • Verb Type: Plural

🎯Exam Tip: If the sentence uses plural possessive pronouns like their, it indicates division, requiring of plural verb.

Distributive Pronouns (Each, Every, Either Neither)

Words like each, every, everyone, someone, nobody, either, and neither are grammatically singular and take singular verbs.

Incorrect: Each of the participants have submitted their entry.❌
Correct: Each of the participants has submitted his/ her entry.✔️

Incorrect: Neither of the two solutions are correct.❌
Correct: Neither of the two solutions is correct.✔️

Amounts, Distances, Time and Units 

When a plural noun refers to a single unit, total sum, distance, time, or weight, it takes a singular verb.

Incorrect: 10 miles are a long distance to walk.❌

Correct: 10 miles is a long distance to walk.✔️
Correct: Fifty thousand rupees was donated to the cause.✔️

Exception: If the sum/units are spent
 all treated individually: Fifty thousand rupees were distributed among the victims.

Quantifiers and Noun Types

 (A number of vs. The number of)

My number of ( + Plural Noun) - Plural Verb (means "many")

A number of candidates have cleared the tier - 1 exam.

The number of ( + Plural Noun) - Singular Verb (Refers to the specific figure/count)

The number of applicants has increased this year.

Other Quantifiers 

All, Most, Some, Plenty, Half depend on the noun following the preposition of:

Some of the milk was spilled.

(Uncountable - Singular)

Some of the books were missing.

(Countable Noun - Plural)

Inversion (Here, There, and Adverbial Openings)

When a sentence starts with here, there, or a negative adverbial clause (Hardly, Scarcely, Seldom), the subject 
comes after the verb.

Incorrect: There is many reasons for his failure.❌

Correct: There are many reasons for his failure.✔️
Correct: Seldom has he seen such dedication. (Subject: he)✔️

Nouns Plural in Form but Singular in Meaning 

Certain nouns and in -s but represent a single subject, discipline, or illness. They take singular verbs.

Subjects/ Fields: Mathematics, Physics, Politics, Economics, Ethics 

Diseases: Measles, Mumps, Rickets 

Games: Billiards, Darts, Draughts

Example: Mathematics is a scoring subject in competitive exams.

Exception: Then fields of study refer to practical application or specific data, they become plural:

His mathematics are weak.(refers to calculation skills)

The statistics show a clear trend.
(refers to data points)

Always plural nouns

Certain nouns exist only in plural form (especially items with two symmetrical parts or compound tools) and take plural verbs unless preceded by "a pair of".

Items: Trousers, scissors, spectacles, binoculars, earnings, surroundings, thanks

Example: My spectacles are missing.

Example: 
With "a pair of": A pair of spectacles has been found on the desk.

Small Mistakes Can Make a Big Difference!

 Common Mistakes You Must Avoid 

  • You and I ❌
  • You and me ✔️
Don't disclose this information. It should be between you and me.

The phrase "It should be between you and me" demonstrates the correct use of pronouns in a prepositional phrase. Here are the grammatical rules that apply:

1. Prepositional Phrases: In English, a prepositional phrase begins with a preposition (in this case, "between") and ends with the object of the preposition, which is typically a noun or pronoun.

2. Objective Case Pronouns: When pronouns are used as the object of a preposition, they should be in the objective case. The objective pronouns include: me, you, him, her, it, us, and them. In the phrase "between you and me," both "you" and "me" are correctly in the objective case.

3. Common Mistake: A frequent mistake is to use subjective pronouns (I, he, she, we, they) in these positions. For example, saying "between you and I" is incorrect because "I" is a subjective pronoun, not an objective one.

Example: Suppose you are discussing a secret or a private matter. You might say, "This information should remain between you and me," indicating that only the two of you should know about it.

By understanding these rules, you can ensure that your use of pronouns is grammatically correct in similar contexts.

  • Didn't played ❌
  • Didn't play ✔️

He didn't play mobile games.

The sentence "He didn't play mobile games" is a simple negative past tense sentence. Let's break down the grammatical rules and structure:

1. Subject: "He" is the subject of the sentence, indicating who performed the action. In English, subject pronouns like "he," "she," "it," "they," etc., are used to identify the doer of the action.

2. Auxiliary Verb: "Didn't" is a contraction of "did not," where "did" is the auxiliary verb used to form the negative past tense. The auxiliary verb "did" is used with the base form of the main verb to indicate actions that did not happen in the past.

3. Main Verb: "Play" is the base form of the verb, which follows "didn't" in negative past tense sentences. Note that the main verb remains in its base form when using "did" as the auxiliary verb.

4. Object: "Mobile games" is the object  of the sentence, specifying what was not played. Objects can be nouns, pronouns, noun phrases, or clauses that receive the action 
of the verb.

Example and Clarification:  

 Positive Sentence: "He played mobile games." Here, "played" is the simple past tense of the verb "play."

 Negative Sentence: "He didn't play mobile games." Here, "didn't" negates the action, and "play" remains in its
 base form.

The use of "didn't" helps clarify that the action of playing mobile games did not occur in the past.
  • Open the fan. ❌
  • Turn on the fan. ✔️
Please turn on the fan, and open all the doors and windows.

The sentence “Please turn on the fan, and open all the doors and windows” follows several grammatical rules that help maintain clarity and coherence. Here’s a breakdown of these rules along with examples to clarify:

1. Imperative Mood: The sentence uses the imperative mood, which is employed to give commands or requests. The subject "you" is understood and not explicitly stated. 

 Example: “Close the window.” (The implied subject is "you.")

2. Parallel Structure: The sentence maintains parallel structure by using two imperative clauses joined by a coordinating conjunction “and.” Both clauses begin with
 a verb phrase, ensuring consistency in style.

 Example: “Wash the dishes, and sweep the floor.” (Both actions are expressed in the same format.)

3. Punctuation: A comma is used before the conjunction “and” to separate the two independent clauses, emphasizing the equal importance of both actions.

 Example: “Turn off the lights, and lock the door.” (The comma helps to clearly separate the two commands.)

4. Politeness Marker: The word “please” is used at the beginning of the sentence to make the request polite and courteous.

 Example: “Please hand me the salt.” (The use of “please” softens the command.)

By following these grammatical rules, the sentence effectively communicates a polite request for multiple actions to be taken.
  • Less friends ❌
  • Fewer friends ✔️
He has fewer friends in comparison to others.

The sentence “He has fewer friends in comparison to others” uses several grammatical rules that can be broken down as follows:

1. Subject-Verb Agreement: The subject “He” is singular, so it takes the singular verb form “has.” This agreement is essential for maintaining grammatical correctness.

2. Comparative Structure: The phrase “in comparison to others” is used to establish a comparison between the number of friends he has and the number of friends other people have. This structure highlights the comparative nature of the statement.

3. Use of “Fewer”: The word “fewer” is used with countable nouns, such as “friends,” to indicate a smaller quantity. It is important to distinguish “fewer” from “less,” which is used with uncountable nouns.

4. Prepositional Phrase: “In comparison to” is a prepositional phrase that helps to introduce the basis of comparison, providing clarity to the sentence.

Example to Clarify: 
Consider the sentence, “She has fewer books than her classmates.” Here, “She” is the subject, “has” is the singular verb, “fewer” indicates a smaller countable quantity (books), and “than her classmates” is the comparative phrase, showing that the number of books she has is less compared to her classmates. 

In both examples, the structure effectively communicates a comparison of quantities using the appropriate grammatical rules.

Pay attention to pronoun-antecedent agreement, ensuring pronouns correctly refer back to their respective nouns.

 Avoid common errors in verb tenses 
by practicing consistency, especially in complex sentences. Brush up on punctuation rules, particularly the use of commas and apostrophes, to enhance clarity. 

Expand your vocabulary to improve word choice and avoid redundancy. Finally, regularly practice writing and seek feedback to refine your grammar skills.













Master 'Who' to 'By whom' Passive Voice Conversion: Rules, Formula & Practice | How to Change 'Who' and 'Whom' Questions from Active to Passive Voice


Master Interrogative Active and Passive Voice Rules: Easy Guide for Competitive Exams 

Wh-Words in Passive Voice: Who vs Whom

Interrogative sentences are broadly divided into two types:

1. Yes/No Questions: Questions that can be answered with yes or no.
   
    Active: Did you watch the movie, "Hanuman Ansh" yesterday?
    Passive: Was the movie, "Hanuman Ansh", watched by you yesterday?

Explanation:

In English grammar, forming the passive voice involves a few key steps:   

Identify the object of the active sentence:

In the active sentence, the object is "the movie, "Hanuman Ansh".


In the passive voice, the object of the active sentence becomes the subject of the passive sentence.


The word "to be" must match the tense of the main verb in the active sentence.
Here, " watch" is in the simple past tense, so "was" is used.


The main verb "watch" becomes "watched".


In passive constructions, the agent (the doer of the action) can be included using "by". Here, "by you" is used.

This structure shifts the focus from the doer of the action to the action itself or the recipient of the action.

2. Wh-Questions: Questions that begin with Wh-words such as who, whom, whose, what, which, when, where, and why.


Yes /No starts with auxiliary verb (Be, Do, Have, Modals)
Wh-Word starts with question word.

Today, we are going to discuss Wh-questions, with a special focus on “Who” and “Whom” in Passive Voice.

Many students find it confusing to change Who into By whom and Whom into Who while transforming active voice into passive voice.

Don't worry! In this lesson, we will understand the rules step by step, using simple formulas and examples to make voice change easier for SSC and other competitive examinations.


Who and Whom in Voice Change

Converting questions that begin with "Who" and "Whom" into Passive Voice can feel tricky because these words shift roles between the subject and the object of a sentence.

Master "Who" and "Whom" quickly with this visual trick - ideal for competitive exams.

Understanding the core mechanics behind these two relative pronouns makes converting any question seamless and accurate.

The Core Concept: Subject vs. Object

Before diving into the formulas, keep this simple rule in mind:

"Who" acts as the Subject ( the doer of the action) in Active Voice.

"Whom" acts as the Object ( the receiver of the action) in Active Voice.

When converting to passive voice, subjects and objects swap places:

Who (Active Subject) - By whom (passive object)
Whom (Active Object) - Who (passive subject)

Questions starting with "Who"

 Since "Who" is the subject performing the action, it moves to the end of the preposition in Passive Voice, changing into " By whom".

Standard Formula:

  • Active: Who + Verb + Object?
  • Passive: By whom + Auxiliary Verb + Object + third form of the verb.

Tense-Wise Breakdown and Examples 

Simple Present Tense 

Formula: By whom + is/ am/are + Object + third form of the verb?
  • Active: Who teaches you French?
  • Passive: By whom are you taught French?

Formula: By whom + was/were + Object + third form of the verb?
  • Active: Who broke the windowpane?
  • Passive: By whom was the windowpane broken?

Formula: By whom + is/am/are/was/were + Object + being + third form of the verb.
  • Active: Who is abusing your friend?
  • Passive: By whom is your friend being abused?

Formula: By whom + has/have/ had + Object + been + third form of the verb?
  • Active: Who has written this application?
  • Passive: By whom has this application been written?
Modals (Can, Could, Will, Should)

Formula: By whom + Modal + Object + be + third form of the verb?
  • Active: Who can solve this miscellaneous exercise?
  • Passive: By whom can this miscellaneous exercise be solved?
Note: In casual or spoken English, starting with Who and ending with by is also common.

For example,

Who was this book written by?

"By whom...." structure is preferred.

Questions Starting with "Whom"

In Active Voice, "Whom" is the object of the verb. 

When converting to Passive Voice, this object becomes the new subject and 
turns into "Who".

Standard Formula 

  • Active: Whom + Auxiliary Verb + Subject + Verb?
  • Passive: Who + Auxiliary Verb + Third form of the verb + by + Subject?

Tense-Wise Breakdown &; Examples 


Active: Whom do you select?
Passive: Who is selected by you?


Active: Whom did the team support?
Passive: Who was supported by the team?


Active: Whom were they searching for?
Passive: Who was being searched for by them?


Active: Whom should we discuss?
Passive: Who should be discussed by us.


  • Active Sentence: Who wrote War and Peace?
  • Passive Conversion: By whom was War and Peace written?
  • Focus Rule: Who - By whom
  • Active Sentence: Whom did you punish?
  • Passive Conversion: Who was punished by you?
  • Focus Rule: Whom - Who
  • Active Sentence: Who has taken my favourite smartwatch?
  • Passive Conversion: By whom has my favourite smartwatch been taken?
  • Focus Rule: Who - By whom
  • Active Sentence: Whom will they appreciate?
  • Passive Conversion: Who will be appreciated by them?
  • Focus Rule: Whom - Who

Practice Exercise ✍️

  • Active: Who is flying a kite?
  • Passive: By whom is a kite being flown?
Explanation:

 Identify the Subject, Verb, and Object:

In the active sentence, 

In passive voice, the object of the active sentence becomes the subject of the passive sentence. Therefore "a kite" becomes the subject.


The original subject "Who" is introduced in the passive sentence with "by", resulting in "By whom".

This is structure emphasizes the action and the recipient of the action rather than the doer.

Use an Appropriate Form of "to be":

The verb "is flying" is changed to the appropriate form of "to be" plus the past participle of the main verb. In this case, "is being flown".


The original subject "Who" is introduced in the passive sentence with "by", resulting in "By whom".

This is structure emphasizes the action and the recipient of the action rather than the doer.

Active Voice:

Who designed the national emblem of India?

Passive Voice:

By whom was the national emblem of India designed?


The sentence begins with "Who", which ask about the doer of the action. When changing this type of question into passive voice, "Who" changes to "By whom".


The verb "designed" is in the Simple Past Tense.

Active Voice Structure:

Who + Second Form of the Verb + Object?

Passive Voice Structure:

By whom + was /were + Object + Third Form of the Verb 


Object in the active voice: The national emblem of India

It becomes the subject in the passive voice

Use the correct helping verb and past participle.
  • The national emblem is singular, so we use "was".
  • The past participle of "design" is "designed".
Retain the question mark (?)

Since the original sentence is an interrogative sentence, the passive sentence must also end with a question mark.

Step by step transformation:

Active Voice 

Who designed the national emblem of India?

Apply the rules 

Who - By whom

Active: Designed (second form of the verb)

Passive: was designed (was + third form of the verb)

Passive Voice 

By whom was the national emblem of India designed?

Exam tips for SSC CGL, and other government exams (Most Important)

Remember this pattern:

Active Voice: Who + second form of the verb + object
  • Active Voice: Who wrote this message?
  • Passive Voice: By whom was this message written?
  • Active Voice: Who invented the thermometer?
  • Passive Voice: By whom was the thermometer invented?
  • Active Voice: Who designed this corridor?
  • Passive Voice: By whom was this corridor designed?
Point to Remember: Don't write "By whom did the national emblem of India designed?"

 The passive voice requires:  was/were + third form of the verb, not did + form of the verb.

Active and Passive Voice 

"Let's Stop Guessing 
and Start Understanding"!

If you are preparing for SSC CGL, SSC Stenographer, SSC CHSL,UPSC, & Other Government Exams, this comprehensive guide will help you understand rules instead of simply memorizing them.

Stop! Confusing while transforming Active Voice to Passive Voice:

Who vs Whom in Voice Change:

 Rules, Formulas and Examples for SSC Exams

One of my followers recently told me, “I am confused about the use of Who and Whom while changing sentences from Active Voice to Passive Voice.”

I advised him to learn the basic formulas and understand how these question words change in the passive voice. I also assured him that I would write a detailed article to clear up his confusion.

In grammar, "rule" and "formula" are related, but they are not exactly the same.

Rule: Explains when and why a grammatical structure is used.

Formula: Gives a fixed pattern to follow when constructing or transforming a sentence.

So, in this article, we will learn how to change “Who” into “By whom” and “Whom” into “Who” in the Passive Voice, with simple explanations, tense-wise formulas, solved examples, and interactive practice questions.

For example,
  • Who - By whom 
  • Whom - Who 
  • Active: Who washed these utensils?
  • Passive: By whom were these utensils washed?
Formula:

Who + V² + object?

→ By whom + was/were + object + V³?

More examples:
  • Active: Who broke these cups?
  • Passive: By whom were these cups broken?
  • Active: Who wrote these letters?
  • Passive: By whom were these letters written?
  • Active: Whom did you teach?
  • Passive: Who was taught by you?
  • Active: Whom did you call?
  • Passive: Who was called by you?
To change an active sentence like "Whom did you call?" into passive voice, we need to make the object of the active sentence the subject of the passive sentence.

 However, since this is a question, the structure changes slightly while maintaining the interrogative form. The passive voice of "Whom did you call?" would be "Who was called by you?"

 Explanation:


In the active sentence, "Whom did you call?"
  •  "whom" is the object
  •  'you' is the subject, 
  •  "call" is the verb.
Change the Structure:

In a passive voice , the object (whom) becomes the subject of the sentence. The verb " call" changes to its past participle form "called".

Rearrange the Sentence:

The sentence becomes " Who was called by you?" Here, "who" takes the place of "whom" in passive voice as the subject of the sentence is indefinite.

 Formula:


Subject + Verb + Object 

Passive Voice (Question Form): 

Question Word (Who/What) + auxiliary verb (was/were) + past participle of the main verb + by + subject 

By following these steps and formula, you can convert questions from active to passive voice while maintaining their interrogative nature.

Important Exam Tip: Always put a question mark (?) at the end of an interrogative sentence in the passive voice, just as you do in the active voice.

Quick Memory Trick:

Choose the correct option:


Who played Minecraft all the time? 

Passive Voice: By whom was Minecraft played all the time?
Explanation: In the simple past tense, the passive voice follows this structure:

Object + was/were + third form of the verb + by + subject 

Point to remember: When changing an interrogative sentence beginning with 
 Who into passive voice, use "By whom". 

By whom has the bone china cup broken?

Who had broken the bone china cup?
Who have broken the bone china cup?
Who has broken the bone china cup?
Who broke the bone china cup?

Answer: Who has broken the bone china cup?
Explanation: When changing a question beginning with “By whom” from passive to active voice, use “Who” as the subject.

Who has seen the latest news?

  1. Have my charger been seen by you?
  2. Has my charger been seen by you?
  3. Had my charger been seen by you?
Active Voice: Who has seen the latest news?
Passive Voice: By whom has the latest news been seen?

Explanation: When changing an interrogative sentence beginning with Who into passive voice, use By whom.

Structure:

Active: Who + has/have + V³ + object?

Passive: By whom + has/have + object + been + V³?

Who wrote the novel," A Noble Name"?

  1. By whom had the novel, "A Noble Name " written?
  2. By whom was the novel, "A Noble Name" written?
  3. By whom was the novel, "A Noble Name" wrote?
