Master Grammatical Error Spotting for SSC CGL by focusing on Subject-Verb Agreement, tenses, pronouns, and prepositions. Quick identification of common errors boosts speed and accuracy.

Rule

Grammatical Error Spotting tests your ability to identify a sentence part containing a grammatical mistake. The key is to read each part carefully, looking for violations of standard English grammar rules. Prioritize speed by quickly scanning for common error types first.

Correct Examples

  1. The committee has decided to postpone the meeting until next week.
  2. Neither of the students was able to solve the complex problem.
  3. She is proficient at playing the piano and singing.
  4. Having finished his work, he went home immediately.
  5. The new policy will be implemented from next month.

    • Incorrect: The list of items are on the table.
    • Correct: The list of items is on the table.
  • Tense Errors
    • Incorrect: He has gone to Mumbai yesterday.
    • Correct: He went to Mumbai yesterday.
  • Pronoun Errors
    • Incorrect: Between you and I, this is a secret.
    • Correct: Between you and me, this is a secret.
  • Preposition Errors

    • Correct: She is good at mathematics.
  • Parallelism
    • Incorrect: He likes to swim, to run, and cycling.
    • Correct: He likes to swim, to run, and to cycle.

    • Correct: He performed well in the exam.
  • Article Usage (a/an/the)
    • Incorrect: He is an European.
    • Correct: He is a European.

Exam Pattern

Questions typically present a sentence divided into three or four parts (A, B, C, D), with one part containing an error. You must identify the part with the error. If there's no error, choose 'No Error' (D or E). Read the entire sentence first to grasp the context before scrutinizing each part.

Detailed Rules & Exceptions

  • Subject-Verb Agreement (Advanced):
    • Collective Nouns: Treat as singular if acting as a unit (e.g., The jury has reached its verdict). Treat as plural if members are acting individually (e.g., The jury are divided in their opinions).
    • Indefinite Pronouns: 'Each', 'every', 'either', 'neither', 'anyone', 'somebody', 'nobody' always take a singular verb (e.g., Each of the students has submitted their assignment).
    • Phrases like 'as well as', 'along with', 'together with': The verb agrees with the first subject (e.g., The captain, along with his team, is celebrating).
  • Pronoun Case: Ensure correct use of subjective (I, he, she, we, they) and objective (me, him, her, us, them) pronouns, especially after prepositions (e.g., for him and me, not for he and I).
  • Tense Consistency: Maintain a consistent tense throughout a sentence or paragraph unless there's a clear reason for a shift (e.g., When I arrived, he was already eating vs. When I arrive, he will be eating).
  • Preposition Traps: Certain words demand specific prepositions. Learn these fixed prepositions (e.g., accused of, fond of, deal with, agree to/with/on).
    • Agree with (a person), agree to (a proposal), agree on (a point/issue).
    • Differ from (things), differ with (person).
  • Adjectives vs. Adverbs: Adjectives modify nouns/pronouns (e.g., He is a good student). Adverbs modify verbs, adjectives, or other adverbs (e.g., He studies well). Avoid using an adjective where an adverb is needed.

Practice Sentences (Spot the Error)

  1. The number of students participating in the competition have increased this year.
  2. He insisted on me to pay the bill immediately.
  3. Scarcely had he reached the station when the train departed.
  4. The manager, as well as his employees, were present at the meeting.
  5. Despite of his efforts, he failed to secure the first position.

Frequently Tested Patterns

  • Subject-Verb Agreement: Always check the subject that the verb is agreeing with, especially with complex subjects or intervening phrases.
  • Tense Errors: Look for conflicting time markers (e.g., 'yesterday' with 'has done').
  • Prepositional Phrases: Verify if the correct preposition is used with specific verbs, nouns, or adjectives.
  • Pronoun Antecedent Agreement: Ensure pronouns agree in number and gender with the nouns they replace.
  • Comparison Errors: Check for correct comparative/superlative forms and proper use of 'than'/'to' (e.g., senior to, better than).

Ensure the verb matches the subject's number (singular/plural). Ignore intervening phrases. Master tricky cases like indefinite pronouns and collective nouns for quick error detection.

Rule

Subject-Verb Agreement (SVA) is fundamental: A singular subject takes a singular verb, and a plural subject takes a plural verb. This is the bedrock of error detection in SSC CGL. The verb must agree with its true subject, not with any noun or pronoun that comes between the subject and the verb.

Correct Examples

  1. The student studies diligently for the exam. (Singular subject 'student' takes singular verb 'studies')
  2. The students study diligently for the exam. (Plural subject 'students' takes plural verb 'study')
  3. One of the books is missing from the shelf. (True subject is 'One', not 'books')
  4. Neither of the solutions is acceptable. (Indefinite pronoun 'Neither' is singular)
  5. The committee has reached a unanimous decision. (Collective noun 'committee' acting as a single unit)

Common Errors

  • Intervening Phrases: Often, phrases like 'along with', 'as well as', 'in addition to', 'with', 'together with', 'besides', 'except', 'no less than', 'rather than' come between the subject and the verb. The verb must agree with the first subject, ignoring these phrases.
    • Incorrect: The captain, along with his players, are celebrating.
    • Correct: The captain, along with his players, is celebrating.
  • Indefinite Pronouns: Words like 'each', 'every', 'either', 'neither', 'anyone', 'someone', 'no one', 'everyone', 'anybody', 'somebody', 'nobody', 'everybody' are always singular and take a singular verb.
    • Incorrect: Each of the boys have a new uniform.
    • Correct: Each of the boys has a new uniform.
  • Collective Nouns: Nouns like 'team', 'committee', 'jury', 'audience', 'family', 'government' can be singular or plural depending on context. If they act as a single unit, use a singular verb. If they act as individuals within the group, use a plural verb.
    • Incorrect: The jury were unanimous in its verdict.
    • Correct: The jury was unanimous in its verdict. (Acting as one unit)
  • Neither...nor / Either...or: When two subjects are joined by 'neither...nor' or 'either...or', the verb agrees with the subject closer to it.
    • Incorrect: Neither the manager nor the employees is responsible.
    • Correct: Neither the manager nor the employees are responsible.

Exam Pattern

SSC CGL typically presents SVA errors in 'Spotting the Error' questions. A sentence is broken into parts (A, B, C, D), and you identify the part with the error. Sometimes, it appears in 'Sentence Improvement' or 'Fill in the Blanks'. The key is to quickly identify the true subject and its number, then check the verb form. Don't get distracted by plural nouns in intervening phrases.

Detailed Rules & Exceptions

  1. Compound Subjects (AND): When two or more subjects are joined by 'and', they usually take a plural verb.
    • Example: John and Mary are going to the party.
    • Exception: If the two subjects refer to the same person/thing or form a single idea, they take a singular verb. (e.g., 'Bread and butter is his favorite breakfast.')
  2. 'A number of' vs. 'The number of':
    • 'A number of' (meaning 'many') takes a plural verb. (e.g., A number of students were absent.)
    • 'The number of' takes a singular verb. (e.g., The number of applicants has increased.)
  3. Expressions of Quantity: When a phrase indicates a portion (e.g., 'some of', 'all of', 'most of', 'half of', 'a lot of', 'none of', 'percentage of'), the verb agrees with the noun in the prepositional phrase.
    • Example: Some of the water is polluted. (Water is singular)
    • Example: Some of the students are late. (Students are plural)
  4. Relative Pronouns (Who, Which, That): The verb in a relative clause agrees with the antecedent of the relative pronoun.
    • Example: He is one of the students who score high marks. (Who refers to 'students', which is plural)
    • Exception: He is the only one of the students who scores high marks. (Who refers to 'one', which is singular)
  5. Titles, Names, Countries: Even if plural in form, titles of books, names of countries, or organizations take a singular verb.
    • Example: 'The Arabian Nights' is a famous collection of stories.
    • Example: The United States is a powerful nation.

Practice Sentences

  1. The quality of the apples (is/are) not good.
    • Answer: is (Subject is 'quality', singular)
  2. Neither the students nor the teacher (was/were) present.
    • Answer: was (Verb agrees with 'teacher', closer subject)
  3. Every man and woman (has/have) the right to vote.
    • Answer: has (When 'every' or 'each' precedes compound subjects, the verb is singular)
  4. Physics (is/are) a difficult subject for many.
    • Answer: is (Subject 'Physics' is a singular proper noun, despite ending in 's')

Frequently Tested Patterns

  • Intervening phrases: Always check the subject before the prepositional phrase or 'along with' type phrase.
  • Indefinite pronouns: Remember 'each', 'every', 'either', 'neither', and '-one/-body' words are always singular.
  • 'Neither...nor' / 'Either...or': The verb agrees with the noun closest to it.
  • Collective Nouns: Context is key – is the group acting as one or as individuals?
  • 'A number of' vs. 'The number of': This is a classic trap. 'A number of' = plural verb; 'The number of' = singular verb.

Master tense consistency and correct aspect usage for SSC CGL. Ensure verbs align with time references and logical sequence to quickly spot errors.

Rule

Verbs must align with the time frame of the action and maintain consistency within a sentence or paragraph. Tense refers to the time of an action (past, present, future), while aspect describes the nature of the action (simple, continuous, perfect, perfect continuous). Errors often arise from illogical temporal sequences or incorrect aspect usage for a given context.

Correct Examples

  1. By the time I reached the station, the train had already left. (Past Perfect for an action completed before another past action)
  2. She has been working on this project since morning. (Present Perfect Continuous for an action started in the past and continuing)
  3. If it rains tomorrow, we will postpone the match. (Simple Present in the 'if' clause for a future condition)
  4. He said that he had completed his assignment. (Past Perfect in reported speech for an action completed before the reporting verb)
  5. While I was studying, my phone rang. (Past Continuous for an ongoing action interrupted by a simple past action)

Common Errors

  • Incorrect: When I reached the office, the meeting already started.

  • Correct: When I reached the office, the meeting had already started. (Use Past Perfect for the earlier action)

  • Incorrect: She is living in Delhi since 2015.

  • Correct: She has been living in Delhi since 2015. (Use Present Perfect Continuous for an action started in the past and continuing to the present)

  • Incorrect: If he will come, I will tell him the news.

  • Correct: If he comes, I will tell him the news. (Use Simple Present in conditional clauses referring to the future)

  • Incorrect: The teacher asked why I am late yesterday.

  • Correct: The teacher asked why I was late yesterday. (Maintain past tense consistency in reported speech)

Exam Pattern

SSC CGL error detection questions frequently test tense consistency, especially with time clauses (e.g., 'before', 'after', 'since', 'for'), conditional sentences, and reported speech. Look for mismatched tenses between clauses, incorrect use of perfect tenses to indicate sequence, or continuous tenses where simple tenses are required, and vice-versa. Pay close attention to adverbs of time (e.g., 'yesterday', 'tomorrow', 'already', 'yet', 'since', 'for').

Detailed Rules & Exceptions

  1. Past Perfect vs. Simple Past: Use Past Perfect (had + V3) for an action that happened before another action in the past. The Simple Past describes the later past action. Example: He realized he had left his keys at home. (Leaving keys happened before realizing).
  2. Present Perfect Continuous vs. Present Perfect: Present Perfect Continuous (has/have been + V-ing) emphasizes the duration of an action that started in the past and continues to the present. Present Perfect (has/have + V3) focuses on the result or completion of an action that happened at an unspecified time in the past or started in the past and continues. Example: She has been studying for five hours (duration). She has finished her homework (result). Stative verbs (know, love, believe) generally don't use continuous forms.
  3. Conditional Sentences (Type 1): For real and possible future conditions, the 'if' clause uses Simple Present, and the main clause uses Simple Future. Example: If you study hard, you will pass the exam.
  4. Reported Speech (Tense Backshift): When the reporting verb is in the past tense, the tense in the reported clause usually shifts backward. Present Simple becomes Past Simple, Present Continuous becomes Past Continuous, Present Perfect becomes Past Perfect, Past Simple becomes Past Perfect. Example: He said, "I am busy." -> He said that he was busy.
  5. Time Clauses with Future Events: In clauses beginning with 'when', 'as soon as', 'until', 'before', 'after', 'while' referring to future events, use Simple Present, not Simple Future. Example: I will call you when I arrive (not 'when I will arrive').

Practice Sentences

  • Incorrect: The patient died before the doctor arrived.

  • Correct: The patient had died before the doctor arrived.

  • Incorrect: She is knowing the answer for a long time.

  • Correct: She has known the answer for a long time. (Stative verb)

  • Incorrect: If I will get a promotion, I will buy a new car.

  • Correct: If I get a promotion, I will buy a new car.

  • Incorrect: He told me that he is going to Mumbai the next day.

  • Correct: He told me that he was going to Mumbai the next day.

Frequently Tested Patterns

  • 'Since' / 'For' + Time: Almost always indicates Present Perfect or Present Perfect Continuous. (e.g., has been raining since morning, have lived here for ten years)
  • 'By the time' + Past Event: Often requires Past Perfect in the main clause. (e.g., By the time he woke up, the sun had risen)
  • Conditional Type 1: 'If + Simple Present, Will + V1'.
  • Reported Speech: Check for consistent tense backshift when the reporting verb is in the past.
  • Adverbs of Time: Words like 'yesterday', 'last week' demand Simple Past; 'now', 'at the moment' demand Present Continuous; 'tomorrow', 'next week' demand Future Tense.
