Why this topic matters · 8 min read
Spotting Errors is a high-frequency, high-scoring topic in SSC CGL English (Tier 1 & 2). You get 4-5 questions per paper where a sentence has 3-4 underlined parts (A, B, C, D) and you pick the one with a grammatical/syntactical error. No error is also an option. Errors involve subject-verb agreement, tense consistency, preposition misuse, pronoun reference, article usage, and parallel structure. Speed + pattern recognition matter more than deep grammar knowledge.
Subject-Verb Agreement (SVA)
The verb must match the subject in number (singular/plural) and person (1st/2nd/3rd). In SSC papers, errors hide when the subject is far from the verb, or when a collective noun or plural-looking singular noun appears. Example: 'The team are playing' is wrong in formal English (should be 'is'); 'news' is singular despite the 's' ending. Watch for intervening phrases that distract you from the real subject.
- Collective nouns (team, committee, family, audience) take singular verb in formal/British English
- Plural nouns ending in 's' (news, physics, measles, scissors) are singular
- Compound subjects joined by 'and' take plural verb; 'or/nor' take verb matching nearest subject
- Intervening phrases (prepositional phrases, appositives) do NOT change the subject
- Indefinite pronouns (everyone, somebody, neither, each) are singular
Tense Consistency & Sequence
All verbs in a sentence/paragraph must follow a logical time sequence. SSC loves testing whether you can spot when tense shifts without reason. If a sentence starts in past tense, it should stay there unless the meaning demands a shift (e.g., universal truth in present). Common trap: mixing simple past with present perfect without cause, or using future tense when narrating a completed action.
- Narration of past events uses simple past consistently
- Present perfect (have/has + past participle) shows action from past to now; don't mix with simple past randomly
- Universal truths stay in simple present even in past narratives
- Conditional sentences: 'If + past, would + base verb' (not 'will')
- Reported speech shifts tense back one step (direct present becomes indirect past)
Preposition Errors
Prepositions are notoriously tricky because they're often idiomatic (no logical rule). SSC tests fixed phrases: 'agree with/to', 'differ from', 'compare with/to', 'in accordance with', 'on behalf of', 'in lieu of'. The error is usually a wrong preposition inserted where a specific one is required by English convention. Memorizing common collocations is faster than trying to reason.
- Agree WITH (person), agree TO (proposal)
- Differ FROM (something else), differ WITH (person) is rare/wrong
- Compare WITH (similarity), compare TO (metaphorical likeness)
- Comply WITH, conform TO, consist OF
- In/on time, at the time, by the time (all different meanings)
Pronoun Reference & Agreement
A pronoun must refer clearly to a noun (antecedent) and match it in number and gender. SSC tests ambiguous references (which noun does 'it' refer to?) and pronoun-antecedent mismatch (plural pronoun for singular noun, or vice versa). Also watch for incorrect use of 'who' vs 'whom' and relative pronouns.
- Pronoun must agree with antecedent in number: 'Each student must submit their work' (singular 'each' + plural 'their' is now accepted, but older tests may mark it wrong)
- Ambiguous reference: 'The book fell off the shelf and it broke' — does 'it' = book or shelf?
- Who (subject), whom (object); 'The man who I met' is wrong (should be 'whom')
- Relative pronoun 'that' for restrictive clauses, 'which' for non-restrictive (though SSC may not strictly test this)
- Avoid dangling pronouns: 'While reading, the phone rang' — who is reading?
Article Usage (A, An, The)
Articles are small but frequently tested. 'A' precedes consonant sounds, 'an' precedes vowel sounds. 'The' is definite (specific noun); 'a/an' is indefinite (general). SSC often tests whether you use 'the' unnecessarily (e.g., 'the electricity' is wrong; 'electricity' is uncountable and generic) or omit it when needed (e.g., 'the sun', 'the moon' always take 'the').
- A/an before consonant/vowel SOUND, not letter: 'a university' (yu- sound), 'an honest man' (silent h)
- Uncountable nouns (water, information, advice) don't take 'a/an'
- Unique nouns (sun, moon, earth, president of India) take 'the'
- Omit article before plural generics: 'Dogs are loyal' (not 'The dogs')
- Use 'the' when noun is specific/previously mentioned or defined by context
Parallel Structure
When listing items or ideas, they must have the same grammatical form. If you start with a noun, continue with nouns; if with a verb, continue with verbs. SSC tests this in sentences with 'and', 'or', 'but', or lists. A common error: 'He likes reading, writing, and to paint' (should be 'reading, writing, painting' — all gerunds).
- In lists, match grammatical form: nouns with nouns, verbs with verbs, adjectives with adjectives
- Correlative pairs (either...or, neither...nor, both...and) must have parallel structure after each part
- Comparisons: 'She is as tall as him' (not 'as tall as he is' in informal English, but formal prefers 'he')
- After 'not only...but also', match structure: 'not only smart but also hardworking' (both adjectives)
Common Idiomatic & Miscellaneous Errors
SSC also tests fixed expressions and less obvious errors: 'used to' (past habit, not 'use to'), 'supposed to' (not 'suppose to'), 'would rather' (not 'would rather to'), double negatives, and incorrect word forms (e.g., 'advise' is verb, 'advice' is noun).
- Used to + base verb (past habit); 'I used to play' not 'I use to play'
- Supposed to, ought to, have to (not 'suppose to', 'ought', 'have')
- Would rather + base verb, not infinitive: 'I would rather go' not 'would rather to go'
- Avoid double negatives: 'I didn't see nothing' is non-standard (use 'didn't see anything')
- Advice (noun), advise (verb); practice (noun/verb US), practise (verb UK)
⚠ Common mistakes to avoid
- Ignoring intervening phrases: 'The list of items ARE ready' — the subject is 'list' (singular), not 'items'; verb should be 'is'. Aspirants focus on the nearest noun instead of the real subject.
- Mixing up prepositions by guessing: 'comply to' instead of 'comply with'. Prepositions are idiomatic; there's no logic. Memorize, don't reason.
- Assuming 'their' is always wrong with singular: Modern English accepts 'Each student submitted their work', but older SSC papers may mark it wrong. Know the exam's standard.
- Overlooking tense shifts in long sentences: A sentence starts in past, then sneaks in present tense mid-way. Read the whole sentence before deciding.
- Confusing 'who' and 'whom': Many aspirants default to 'who' because it's more common in speech. Remember: whom = object (him/her/whom rhyme).
🧠 Memory aids
- SVA Trick: Cover the intervening phrase with your finger. 'The team [of players] are' becomes 'The team are' — now you see the real subject.
- Preposition Mnemonic: CWDC = Comply With, Differ From, Compare With/To, Consist Of. Make your own list of 10 fixed phrases and drill them.
- Tense Check: Ask 'When did this happen?' If all events are in the past, use simple past consistently. If one is universal truth, keep it present.
- Pronoun = Him/Her/Whom: If you can replace the pronoun with 'him' or 'her', use 'whom' or 'him'. If 'he' or 'she', use 'who' or 'he'.
🎯 SSC CGL exam tips
- SSC Tier 1 gives 4-5 Spotting Error questions in 75 minutes (English section ~25 min). Speed is critical; spend max 1 min per question. Skim, spot the error, move on.
- Recent papers (2022-2024) emphasize SVA, tense consistency, and prepositions over rare grammar rules. Focus on these three; they account for ~60% of errors.
- The 'No Error' option appears in ~20-30% of questions. Don't assume there's always an error. If you've checked all four parts and found nothing, pick 'No Error' confidently.
- Errors are often in parts B and C (middle of the sentence) because aspirants rush through them. Slow down for the middle parts.
- SSC uses formal/British English standards. 'The team is' (formal) may be preferred over 'the team are' (British collective), but check your study material's standard. Consistency within the exam matters.
