Spotting Errors is a high-frequency GK + English combo in SSC GD (2-4 questions per paper). You are given a sentence with 4 marked parts (A, B, C, D) and must identify which part contains a grammatical, spelling, or usage error — or say 'No error'. This tests basic grammar rules: subject-verb agreement, tense consistency, preposition usage, article misuse, and pronoun errors. Most errors are intentional and obvious once you know the rule.
Subject-Verb Agreement (SVA) — Most Common Error Type
The verb must match the subject in number (singular or plural) and person. In SSC GD, examiners love hiding plural subjects with singular verbs or vice versa. Watch for collective nouns (team, group, committee) which can be singular or plural depending on context. Also watch for subjects separated from verbs by long phrases — the error hides in the gap.
- Singular subject takes singular verb: The boy runs (not run)
- Plural subject takes plural verb: The boys run (not runs)
- Collective nouns (team, group, family) usually singular in Indian English: The team is strong
- When subject and verb are separated by a phrase, match the real subject, not the nearest noun
- Either...or / Neither...nor: verb agrees with the nearer subject
- Each, every, someone, nobody, everyone = always singular
Tense Consistency — Time Logic Errors
A sentence must maintain consistent tense unless there is a logical reason to shift. SSC GD tests whether you can spot tense jumps. If a sentence starts in past tense, it should stay there unless describing something that happened before (past perfect) or a universal truth (simple present). Common trap: mixing simple past with present perfect without reason.
- Simple past for completed action: He went to Delhi yesterday
- Present perfect for recent action with present relevance: He has gone to Delhi (just left)
- Past perfect for action before another past action: He had gone before I arrived
- Avoid jumping tenses in the same sentence without logical cause
- Universal truths stay in simple present even in past narratives: He said that water boils at 100°C
- Watch for sentences with multiple verbs — all must align logically
Article Misuse — A, An, The Errors
Articles are small but frequently tested. Use 'a' before consonant sounds, 'an' before vowel sounds. Use 'the' for specific/known things, no article for general statements. Indian English sometimes drops articles where British English requires them — SSC GD follows British/formal rules.
- A before consonant sound: a book, a university (u sounds like 'yoo')
- An before vowel sound: an apple, an hour (h is silent)
- The for specific/known: the Prime Minister, the Taj Mahal
- No article for general plurals: Dogs are loyal (not The dogs are loyal)
- Common error: 'a unique' (wrong — unique starts with consonant sound 'yoo')
- Watch for missing 'the' before superlatives: He is the tallest boy (not tallest boy)
Preposition Errors — In, On, At, With, By
Prepositions are notoriously tricky because rules are partly idiomatic. SSC GD tests common preposition pairs: in time vs on time, at night vs in the night, agree with vs agree to. Memorize the most frequent patterns rather than trying to understand all rules.
- In time = with enough time to spare; On time = exactly at the scheduled moment
- At night, at dawn, at noon; In the morning, in the afternoon, in the evening
- Agree with (a person), agree to (a proposal)
- Differ from (be different), differ with (disagree)
- Depend on (rely), depend upon (also correct but less common)
- Reason for, reason with, reason about (watch the preposition after 'reason')
Pronoun Errors — Case, Agreement, Reference
Pronouns must match their antecedent (the noun they replace) in number and gender. Case errors occur when you use 'me' instead of 'I' or vice versa. Ambiguous reference (unclear which noun the pronoun refers to) is also tested. Watch for singular they vs plural they confusion.
- Pronoun case: I/we/he/she (subject), me/us/him/her (object), mine/ours/his/hers (possessive)
- Pronoun-antecedent agreement: The girl lost her book (not their book)
- Avoid ambiguous reference: When John met Ram, he was happy (unclear who is happy)
- Each, everyone, someone take singular pronouns: Everyone brought his/her book (not their)
- Modern usage allows singular they for unknown gender, but SSC GD prefers he/she or he/his
Common Word Misuse — Confusing Pairs
SSC GD loves testing commonly confused words. These are not grammar errors technically, but usage errors. Learn the difference between affect/effect, its/it's, loose/lose, principal/principle, complement/compliment.
- Affect (verb: to influence), Effect (noun: result, or verb: to bring about)
- Its (possessive), It's (it is)
- Loose (adjective: not tight), Lose (verb: to misplace)
- Principal (main, or head of school), Principle (rule, concept)
- Complement (something that completes), Compliment (praise)
- Stationary (not moving), Stationery (writing materials)
⚠ Common mistakes to avoid
- Ignoring the subject-verb gap: A long phrase between subject and verb tricks you into matching the wrong noun. Always identify the real subject first.
- Mixing tenses without reason: Jumping from past to present in one sentence without logical cause. Check if the tense shift is justified by meaning.
- Confusing 'a' and 'an' by letter instead of sound: 'An university' is wrong because 'u' sounds like 'yoo' (consonant sound). Go by sound, not spelling.
- Forgetting that collective nouns can be singular: 'The team are playing' is wrong in formal English — should be 'The team is playing'.
- Picking 'No error' too quickly: If you don't spot an error in 10 seconds, re-read carefully. Most sentences have exactly one error planted deliberately.
🧠 Memory aids
- SVA Rule: Subject and Verb must be SAME number — Singular subject = singular verb, Plural subject = plural verb. Think of them as a matching pair.
- Tense Timeline: Past Perfect (before) > Simple Past (then) > Present Perfect (just now) > Simple Present (always true). Keep events in chronological order.
- Article Sound Check: A before Consonant sound, An before vowel sound. Say the word aloud — if it starts with a vowel SOUND, use 'an'.
- Preposition Pairs: IN time (spare time), ON time (exact time), AT night (specific moment), IN morning (duration). Memorize as fixed phrases, not rules.
- Pronoun Match: Pronoun = Antecedent's clone. If antecedent is singular, pronoun is singular. If antecedent is plural, pronoun is plural.
🎯 SSC GD exam tips
- SSC GD Spotting Errors typically has 2-4 questions per paper, each worth 1 mark. Total time budget: 3-4 minutes for all error questions. Read fast, identify the error type, eliminate wrong options.
- The error is ALWAYS in one of the four parts (A, B, C, D). If you cannot spot it in 15 seconds, mark 'No error' (option D) — don't waste time. Come back if time permits.
- Recent papers show heavy focus on Subject-Verb Agreement and Tense Consistency (60% of error questions). Prepositions and articles are secondary. Prioritize SVA and tense rules in your revision.
- Errors are usually obvious once you know the rule — examiners don't hide errors in complex structures. If you know the grammar rule, you will spot the error. If you don't know the rule, you will guess. So focus on learning rules, not tricks.
- Watch for sentences with multiple verbs or clauses. The error often hides in the second clause. Example: 'He went to the market and buys vegetables' — tense mismatch in the second verb.
- No error questions are rare but possible. If all four parts are grammatically correct, mark 'No error'. Don't assume there must be an error.
