Spot the Error — SSC MTS Study Notes

Overview

Spot the Error questions test your understanding of English grammar rules by asking you to identify which part of a sentence contains a mistake. In SSC MTS Paper 1, you'll typically see 2–3 such questions where a sentence is divided into three or four parts (labeled A, B, C, D), and you must pick the part with the grammatical error. Sometimes all parts are correct, making "No error" the right answer.

This topic matters because it directly assesses your grasp of subject-verb agreement, tenses, prepositions, articles, pronouns, and sentence structure—all fundamental to English proficiency. Unlike comprehension or vocabulary questions where context helps, error spotting demands precise knowledge of grammar rules. The good news: errors follow predictable patterns. Once you recognize the common mistake types, you can systematically eliminate wrong options and spot errors quickly under exam pressure.

Mastering this topic requires two skills: knowing the grammar rules and training your ear to "hear" what sounds wrong. Regular practice transforms grammar theory into instinct, helping you identify errors in seconds rather than minutes.

Key Concepts

• **Subject-Verb Agreement**: The verb must match the subject in number (singular/plural) and person. Collective nouns, indefinite pronouns, and phrases between subject and verb often create confusion.

• **Tense Consistency**: Within a sentence or related clauses, tenses must logically align. Mixing past and present without reason signals an error.

• **Preposition Usage**: English prepositions are idiomatic—certain verbs and adjectives pair with specific prepositions (e.g., "good at," not "good in"). Wrong preposition choices are frequent error types.

• **Article Errors**: "A," "an," and "the" have specific rules. Omitting necessary articles or adding unnecessary ones creates errors, especially with countable/uncountable nouns.

• **Pronoun-Antecedent Agreement**: Pronouns must agree with their antecedents in number, gender, and person. Ambiguous pronoun references also constitute errors.

• **Modifier Placement**: Misplaced modifiers create confusion about what word or phrase is being modified. Dangling modifiers have no clear word to modify at all.

• **Redundancy and Wordiness**: Using two words that mean the same thing (e.g., "revert back") or unnecessary repetition signals poor construction.

• **Comparison Structures**: Comparative and superlative forms must be grammatically complete and logical, comparing like items with proper degree words.

Key Facts

1. **Common Error Zones**: Subject-verb disagreement (30%), wrong preposition (20%), tense errors (15%), article mistakes (10%), pronoun errors (10%), others (15%).

2. **Either/Neither Rule**: "Either" and "neither" are singular and take singular verbs. "Either of the boys is" not "are."

3. **Collective Nouns**: Words like "team," "jury," "committee" are singular when acting as one unit, plural when emphasizing individual members.

4. **Verb + Preposition Pairs**: Memorize fixed combinations — "depend on," "differ from," "composed of," "die of," "good at," "afraid of."

5. **Many a/More than one**: Despite plural meaning, these take singular verbs: "Many a student has failed."

6. **One of + Plural Noun + Singular Verb**: "One of the students is absent" (not "are") because "one" is the subject.

7. **Present Perfect Usage**: Use with "since" (point in time) and "for" (duration). "I have lived here since 2020 / for three years."

8. **Double Negatives**: Two negatives make a positive in English. "I don't have no money" is wrong; use "I don't have any money."

Worked Examples

**Example 1:** Sentence: "The number of students / in the classroom / are increasing / every year." Parts: (A) The number of students / (B) in the classroom / (C) are increasing / (D) every year

**Solution:** Step 1: Identify the subject — "The number" (singular), not "students." Step 2: Check verb agreement — "are" is plural, but subject is singular. Step 3: Error in part C. Should be "is increasing." **Answer: C**

---

**Example 2:** Sentence: "She is / senior than / me in / the office." Parts: (A) She is / (B) senior than / (C) me in / (D) the office

**Solution:** Step 1: "Senior" is a comparative adjective but doesn't take "than"—it takes "to." Step 2: Correct form: "senior to me." Step 3: Error in part B. **Answer: B**

---

**Example 3:** Sentence: "Neither the manager / nor the employees / was aware of / the new policy." Parts: (A) Neither the manager / (B) nor the employees / (C) was aware of / (D) the new policy

**Solution:** Step 1: In "neither...nor" constructions, verb agrees with the nearest subject—"employees" (plural). Step 2: "Was" is singular, should be "were." Step 3: Error in part C. **Answer: C**

Common Mistakes

**Mistake 1: Ignoring the True Subject** Wrong thinking: "The bouquet of roses are beautiful" sounds fine because "roses" is plural. Correct fix: Subject is "bouquet" (singular), so verb must be "is." Phrases between subject and verb don't affect agreement.

**Mistake 2: Confusing "Less" and "Fewer"** Wrong thinking: "Less people attended" seems acceptable. Correct fix: Use "fewer" with countable nouns (people), "less" with uncountable (water). Correct: "Fewer people attended."

**Mistake 3: Mixing Up "Since" and "For"** Wrong thinking: "I have been working here since five years." Correct fix: "Since" marks a starting point (since 2019), "for" marks duration (for five years). Correct: "for five years."

**Mistake 4: Missing Parallel Structure** Wrong thinking: "She likes reading, to swim, and jogging" looks complete. Correct fix: List items must be in parallel form—all gerunds or all infinitives. Correct: "reading, swimming, and jogging."

**Mistake 5: Overlooking "No Error" Option** Wrong thinking: Force-fitting an error because every question must have one. Correct fix: Some sentences are correct. If all parts follow grammar rules, confidently choose "No error" rather than second-guessing.

Quick Reference

• **Subject far from verb?** Mentally remove middle words to check agreement.
• **Each, every, one, everyone, someone** → always singular verb.
• **Neither/nor, either/or** → verb agrees with nearest subject.
• **Check prepositions** against common verb-preposition pairs (differ from, comply with, capable of).
• **Tense must match time markers** — "yesterday" requires past, "since" requires present perfect.
• **"The number" = singular; "A number" = plural** in verb agreement.
