Error Spotting — Study Notes

Overview

Error spotting tests your ability to identify grammatical mistakes in written English. In SSC CHSL Tier 1, you'll see sentences divided into three or four parts (A, B, C, D or A, B, C with a "No error" option). Your job is to pinpoint which segment contains the error. This section typically carries 3–5 questions and directly tests grammar fundamentals rather than vocabulary or comprehension.

Mastering error spotting requires knowing common grammar rules and recognizing patterns in how these rules are violated. The errors are usually subtle violations of subject-verb agreement, tense consistency, preposition usage, article rules, or pronoun reference. Strong performance here builds confidence because the answers are definitive—once you know the rule, the error becomes obvious.

Focus on the most frequently tested error types: subject-verb agreement, tense errors, preposition confusion, article misuse, and pronoun errors. These five categories cover roughly 80% of all error spotting questions in SSC CHSL. Regular practice trains your eye to spot violations quickly, which is essential under time pressure.

Key Concepts

• **Subject-Verb Agreement**: The verb must match the subject in number and person. Singular subjects take singular verbs; plural subjects take plural verbs. Watch for intervening phrases that separate subject and verb—they often mislead test-takers.

• **Tense Consistency**: Verbs in a sentence or connected clauses must follow logical time sequence. Mixing past and present inappropriately or using wrong forms of irregular verbs are common traps.

• **Preposition Usage**: Certain verbs, adjectives, and nouns demand specific prepositions. "Differ from" not "differ with"; "comprised of" is incorrect (use "comprises" or "composed of").

• **Article Errors**: Incorrect use of a/an/the or missing articles where required. Countable singular nouns need an article; uncountable nouns generally don't take "a/an".

• **Pronoun Reference and Agreement**: Pronouns must agree with their antecedents in number, gender, and person. Ambiguous pronoun reference (unclear what the pronoun refers to) is also tested.

• **Modifier Placement**: Misplaced or dangling modifiers create confusion about what is being modified. The modifier should be adjacent to the word it describes.

• **Redundancy and Wordiness**: Using two words that mean the same thing (like "revert back") or unnecessary repetition creates errors, though this is less common than pure grammar violations.

• **Comparative and Superlative Forms**: Using "more better" instead of "better", or "most unique" (unique has no degrees) are typical mistakes. Know when to use -er/-est versus more/most.

Key Facts

• **Each/Every/Either/Neither** are singular and take singular verbs. "Each of the boys has" not "have".

• **Collective nouns** (team, committee, family) are usually singular in Indian English: "The team is playing well."

• **Data, criteria, phenomena** are plural; their singulars are datum, criterion, phenomenon.

• **None** can be singular or plural depending on context, but in SSC typically treated as singular: "None of them is ready."

• **Since** indicates a point in time and pairs with present perfect; **for** indicates duration: "I have lived here since 2010 / for five years."

• **Between** is for two items; **among** is for more than two.

• **Less** is for uncountable; **fewer** is for countable: "less water, fewer bottles".

• **Lay** (transitive, needs object) vs **lie** (intransitive): "I will lay the book down" vs "I will lie on the bed."

Worked Examples

**Example 1**: Identify the error. (A) One of my friends / (B) are going to / (C) America next month. / (D) No error.

**Solution**: Part (B) contains the error. "One of my friends" is a singular subject (the word "one" is the subject, not "friends"). The correct verb is "is going" not "are going". The phrase "of my friends" is just a prepositional phrase modifying "one". **Answer**: (B)

---

**Example 2**: Identify the error. (A) She has been living / (B) in Delhi / (C) since five years. / (D) No error.

**Solution**: Part (C) has the error. "Since" requires a point in time (since 2019, since Monday), while "for" indicates duration. The correct phrase is "for five years" or "since 2019" (if she came in 2019). Here we need "for five years" because "five years" is a duration. **Answer**: (C)

---

**Example 3**: Identify the error. (A) The number of students / (B) in the classroom / (C) are very high. / (D) No error.

**Solution**: Part (C) is wrong. "The number of students" is a singular subject—"number" is the head noun. Use "is very high" not "are". (Note: "A number of students" would be plural and take "are", but "the number" is always singular.) **Answer**: (C)

---

**Example 4**: Identify the error. (A) He is / (B) senior than / (C) me. / (D) No error.

**Solution**: Part (B) is incorrect. "Senior" is not a comparative adjective that takes "than". The correct form is "senior to". Words like senior, junior, superior, inferior, prefer take "to" not "than". **Answer**: (B)

Common Mistakes

**Mistake**: Thinking the verb agrees with the nearest noun rather than the actual subject. **Fix**: Identify the true subject by removing prepositional phrases. In "The quality of the mangoes is good," "quality" is the subject, not "mangoes."

**Mistake**: Using "since" with a duration instead of a point in time. **Fix**: Remember: "since" = point (since Monday, since 2015); "for" = duration (for two hours, for ten years). Don't mix them up.

**Mistake**: Treating collective nouns as plural (American style) in SSC context. **Fix**: In Indian English exams, collective nouns like team, committee, government are typically singular: "The committee has decided."

**Mistake**: Confusing "less" and "fewer"; using "less" with countable nouns. **Fix**: Use "fewer" for countable items you can number (fewer apples, fewer people), "less" for mass/uncountable (less sugar, less time).

**Mistake**: Ignoring pronoun-antecedent agreement in number or gender. **Fix**: Make sure pronouns match their referents. "Each student must bring their book" is now acceptable informally, but SSC often prefers "his book" or "his or her book" for singular antecedents.

**Mistake**: Missing articles before singular countable nouns in definite contexts. **Fix**: Singular countable nouns generally need an article: "He is a teacher" not "He is teacher." Exception: titles and certain expressions ("She became chairperson").

Quick Reference

• Subject separated from verb by phrases—ignore the phrase, match verb to actual subject.

• Singular subjects: each, every, everyone, someone, nobody, either, neither—all take singular verbs.

• "One of the + plural noun" is singular; "a number of + plural noun" is plural.

• Since = point in time; for = duration; use present perfect with both.

• Prepositions to memorize: senior/junior/superior/inferior/prefer + **to**; different + **from**; comprised + no preposition; composed + **of**.

• Less (uncountable) vs fewer (countable); between (two) vs among (many).
