By the end of this chapter you'll be able to…

  • 1Locate the true subject past interrupters (as well as, along with) and apply agreement rules including either/or and collective nouns
  • 2Use time markers (since/for/ago/by the time) to police tense sequence, conditionals and time-clause rules
  • 3Catch pronoun errors: case after prepositions and 'let', redundant subjects, reflexive verbs, who/whom
  • 4Apply the no-preposition verb list (discuss, comprise, resemble, marry…) and the fixed preposition pairs
  • 5Enforce welded conjunction pairs (no sooner…than, hardly…when) and parallelism in lists
  • 6Run the six-step scanning algorithm and choose 'No error' with confidence when nothing survives it

Why this chapter matters in SSC CGL
Error spotting is the anchor grammar topic of SSC English: 2–3 Tier-1 and 4–6 Tier-2 questions directly, and the identical rule list powers Sentence Improvement and Fill-in-the-Blanks — together 10–15 questions of the paper that decides 35% of your merit. The rule set is finite (~25 points on rotation), which makes this the highest-certainty prep in the English section: learn the list, stop trusting your ear.

Error Spotting — SSC CGL English

Error-spotting questions are not a vocabulary test and not an "ear" test — they are a rule test, and the rule list is short. Every year the same 25 grammar points rotate through the papers wearing new sentences. Aspirants who trust their ear score ~60%; aspirants who check the rule list score 90%+, because SSC deliberately writes sentences that sound fine and break a rule (or sound wrong and are correct).


1. What SSC actually asks

A sentence divided into parts (a)/(b)/(c)/(d — "No error"). You name the faulty part. Tier 1: 2–3 Q · Tier 2: 4–6 Q. The error distribution across PYQs:

Rule familyShare
Subject–verb agreement~20%
Tense & time markers~15%
Pronoun (case, redundancy, agreement)~12%
Prepositions (wrong / redundant / missing)~12%
Articles~10%
Conjunction pairs & parallelism~10%
Adjective/adverb confusion, comparison~10%
Noun number & confusables~10%

2. Subject–verb agreement — the top scorer

  1. Ignore the interrupting phrase. "The quality of the mangoes were good" ✗ → was (subject = quality). Phrases like along with, as well as, together with, and not, in addition to do not change the subject: "The captain, along with the players, was felicitated."
  2. Either/or, neither/nor: verb agrees with the nearer subject: "Neither the students nor the teacher was present."
  3. Each, every, everyone, anybody, nobody → singular verb and singular pronoun: "Each of the boys has done his duty."
  4. Collective nouns (committee, jury, team) → singular when acting as one body; plural when members differ: "The jury was unanimous" / "The jury were divided."
  5. Uncountable classics — these are singular and take no plural -s: furniture, advice, information, luggage, machinery, scenery, poetry, hair, news, knowledge, stationery. "Advices"/"informations" are always wrong.
  6. Plural-form singulars: news, physics, mathematics, politics (as a subject) → singular. Pair nouns: scissors, trousers, spectacles → plural.
  7. "The number of" → singular; "A number of" → plural.
  8. One of the + plural noun + singular verb: "One of the boys was…" — and in relative clauses, "one of the boys who were…" (the who refers to boys).

3. Tense — sequence and the time-marker giveaways

  1. Since/for: since + point of time, for + duration; both usually demand perfect (continuous): "He has been working here since 2019 / for five years."
  2. "Ago" pairs with past simple, never present perfect: "He left an hour ago" — "has left an hour ago" ✗.
  3. When two past actions occur in sequence, the earlier takes past perfect: "The train had left before we reached."
  4. If-clauses: if + present → will; if + past → would; if + had + V3 → would have + V3. Never double the "would": "If he would have come" ✗ → "If he had come".
  5. Universal truths stay in present even after past reporting: "The teacher said that the earth revolves…"
  6. Time and condition clauses reject "will": "I will call you when I reach (not will reach)."

4. Pronouns — case and redundancy

  1. Case after "than/as": "He is taller than I (am)" — formal SSC answer, though the trap usually lies elsewhere; more common is object case after prepositions: "between you and me" (never "between you and I").
  2. Subject double-up is an error: "My brother he works…" ✗.
  3. "Let" takes object case: "Let him and me go."
  4. Reflexives: enjoy, absent, avail, pride, acquaint take a reflexive — "He absented himself"; but "He hid himself" vs preferred "The thief hid" — SSC tests missing/extra reflexives.
  5. who vs whom — subject vs object: "The man who I thought was honest" vs "The man whom I trusted."
  6. Its/it's, whose/who's — possessive vs contraction.

5. Articles, prepositions, conjunctions

Articles: an before vowel sound (an hour, an MLA, a university, a one-rupee note); the with superlatives, unique objects, rivers/seas/mountain ranges, and "the same/the only"; no article with languages, meals, abstract nouns used generally.

Preposition classics SSC recycles:

  • discuss (not "discuss about"), describe, order, demand, attack, resemble, marry, lack — take no preposition.
  • comprise = "consist of" — "comprise of" ✗.
  • prefer X to Y (not "than"), senior/junior/superior/inferior to.
  • different from, die of a disease, deal in goods / deal with people, good at, congratulate on, accused of, charged with.
  • since/for (time), between two / among many, beside (next to) / besides (in addition to).

Conjunction pairs are welded: not only…but also, either…or, neither…nor, no sooner…than, hardly/scarcely…when, lest…should, both…and, so…that. "No sooner did he arrive when" ✗ → than. Also parallelism: the elements joined must match in form — "She likes singing, dancing and to paint" ✗.


6. Adjectives, adverbs & comparison

  1. Linking verbs take adjectives: "The flowers smell sweet (not sweetly)"; feel bad, taste good.
  2. Double comparatives are errors: "more better", "most tallest" ✗.
  3. Comparative with two, superlative with three+: "the taller of the two".
  4. Than + any other: "better than any other boy in the class" (not "any boy" — he'd be better than himself).
  5. Absolute adjectives (unique, perfect, complete, ideal) resist "very/more": "more unique" ✗.
  6. Confusable pairs: elder/older (elder = family), farther/further (distance/addition), less/fewer (uncountable/countable), much/many, little/a little/the little.

7. The scanning algorithm (exam-hall version)

Read the sentence once, then interrogate parts in this order:

  1. Find the verb → find its true subject (skip the interrupters). Agreement OK?
  2. Scan for time markers (since, for, ago, yesterday, by the time) → tense consistent?
  3. Check every pronoun — case, number, necessity.
  4. Check every preposition against the verb/adjective it follows.
  5. Check the welded pairs and parallelism if the sentence has a list or paired conjunction.
  6. Nothing found after two passes → "No error" is a real answer (SSC uses it ~15–20% of the time). Do not invent an error to avoid choosing (d).

8. Solved PYQ-style examples

Q1. (a) One of my friend / (b) is going abroad / (c) for higher studies. / (d) No error Answer: (a) — "one of the/my + plural noun": one of my friends.

Q2. (a) The teacher as well as the students / (b) were present / (c) at the seminar. / (d) No error Answer: (b) — "as well as" doesn't pluralise; subject = teacher → was.

Q3. (a) He has been living in Delhi / (b) since five years / (c) with his uncle. / (d) No error Answer: (b) — duration takes for: for five years.

Q4. (a) No sooner did the bell ring / (b) when the students / (c) rushed out of the class. / (d) No error Answer: (b)no sooner…than.

Q5. (a) The committee discussed about / (b) the new proposal / (c) for over an hour. / (d) No error Answer: (a)discuss takes no preposition.

Q6. (a) Being a rainy day, / (b) Vijay decided to stay / (c) at home and read. / (d) No error Answer: (a) — dangling participle: It being a rainy day… (the subject of "being" isn't Vijay).

Key formulas & results

Everything to memorise for the exam hall, in one card. Screenshot this for revision.

Interrupter rule
with / along with / as well as / together with / and not → subject unchanged
'The captain, along with the players, WAS…'
Nearer-subject rule
either…or / neither…nor → verb agrees with the NEARER subject
'Neither the students nor the teacher WAS present.'
Singular battalion
each, every, everyone, either, neither, anybody, nobody → singular verb + singular pronoun
'Each of the boys HAS done HIS duty.'
Uncountables
furniture, advice, information, luggage, news, hair, scenery, machinery, stationery → no plural, singular verb
'Advices' and 'informations' are always wrong.
Number rule
'The number of' → singular · 'A number of' → plural
'The number of accidents HAS increased.'
since/for/ago
since + point · for + duration · ago + past simple
'has left an hour ago' is always wrong.
Conditionals
if + present → will · if + past → would · if + had V3 → would have V3
Never 'if he would have' — the if-clause carries had.
Welded pairs
no sooner…than · hardly/scarcely…when · not only…but also · lest…should
The partner word is non-negotiable.
No-preposition verbs
discuss, describe, order, demand, attack, resemble, marry, lack, comprise
'Discuss about' / 'comprise of' — instant errors.
Fixed prepositions
prefer TO · superior TO · different FROM · congratulate ON · accused OF · charged WITH · die OF
Memorise as pairs, not rules.
Comparison rules
two → comparative · than any OTHER · no double comparatives · absolute adjectives take no 'more'
'More unique', 'more better' — errors.
Linking verbs
smell/taste/feel/look/sound + adjective
'The flowers smell sweet', 'I feel bad'.
⚠️

Traps SSC CGL sets — and how to dodge them

These are the exact option-traps and misreads that cost marks under negative marking.

WATCH OUT
Matching the verb to the nearest noun instead of the true subject
Bracket the interrupting phrase ('of the mangoes', 'along with the players') and read subject + verb directly: 'The quality … was good.'
WATCH OUT
Trusting the ear — passing sentences that 'sound right'
SSC writes euphonic errors ('discuss about', 'since five years') and awkward-but-correct sentences. Run the six-step algorithm; the ear is a tiebreaker, never the judge.
WATCH OUT
Avoiding 'No error' because it feels like giving up
'No error' is correct in roughly 1 of every 5–6 questions. If two full passes of the algorithm find nothing, choose (d) and move — inventing an error costs the mark AND the negative.
WATCH OUT
Fixing the part that merely sounds odd instead of the part that breaks a rule
Name the rule before marking the option. If you cannot name the rule being broken, you haven't found the error yet.
WATCH OUT
Missing plural after 'one of the'
'One of the + PLURAL noun' always — 'one of my friend' is the single most repeated SSC error-spotting plant.
WATCH OUT
Overlooking dangling participles ('Being a rainy day, Vijay stayed home')
The -ing phrase's hidden subject must equal the main clause's subject. If it doesn't (Vijay isn't the rainy day), that part is the error.

5-minute revision

The whole chapter, distilled. Read this the night before the exam.

  • Find the verb → find its TRUE subject; bracket interrupters (along with, as well as).
  • Neither…nor → nearer subject. Each/every/anybody → singular verb AND pronoun.
  • The number of → singular; a number of → plural. One of the + plural noun.
  • since + point, for + duration, ago + past simple; time clauses reject 'will'.
  • If-clause carries 'had', never 'would have'. Universal truths stay present.
  • No-preposition verbs: discuss, describe, order, demand, attack, resemble, marry, comprise.
  • prefer TO, superior TO, different FROM, congratulate ON, accused OF, charged WITH.
  • no sooner…THAN, hardly…WHEN, lest…SHOULD, not only…BUT ALSO; lists must be parallel.
  • Uncountables never pluralise: advice, information, furniture, luggage, news, hair.
  • than any OTHER; no double comparatives; linking verbs take adjectives (smell sweet).
  • 'No error' is right ~1 in 5 — never invent an error.

SSC CGL question blueprint

How this topic is asked, tier by tier — so you can prep to the pattern.

Typical weightage: Tier 1: 4–6 marks (2–3 Q × 2) · Tier 2: 12–18 marks (4–6 Q × 3)

Question styleMarks eachTypical countWhat it tests
Classic 4-part sentence2–32–4The 25-rule rotation, one rule per sentence
'Select the erroneous segment'2–31–2Same rules, Tier-2 phrasing with longer sentences
Prep strategy
  • Week 1: one rule family per day (agreement → tense → pronouns → prepositions → articles → pairs → comparison).
  • Week 2: 20 PYQs daily, writing the rule name against every answer.
  • Maintain a personal 'trap list' of the rules YOU miss — the last-day revision sheet writes itself.

Exam-hall strategy

Battle-tested tips from mentors and toppers for this topic under the sectional clock.

  1. Run the fixed scan order: subject–verb → time markers → pronouns → prepositions → pairs/parallelism.
  2. Name the rule before marking the option; no name, no answer.
  3. Bracket interrupters instantly — they exist to hide the subject.
  4. Time markers (since/for/ago) resolve tense questions in five seconds; scan for them early.
  5. Choose 'No error' after two clean passes — about one in five questions is clean.
  6. Budget 30–40 seconds per question in Tier 1; the rules make it mechanical.

Beyond the exam

Where this skill shows up in the job you're competing for — and in life.

Official drafting

CGL posts are noting-and-drafting jobs — file notings with grammar errors get returned by section officers.

Every descriptive exam

The same rules police your essay and letter in descriptive papers (CHSL Tier 2, bank mains, CAPF).

Professional email

Agreement and tense slips are the most-noticed errors in workplace writing.

Editing & review skills

The scanning algorithm is literally a copy-editor's checklist — a transferable professional skill.

Where else this topic is tested

Prepare once, score in every exam that asks it.

SSC CHSL / CPO / MTSVery high — identical rule rotation
IBPS / SBI (English)Very high — error spotting is a banking fixture
CDS (English)Very high — the CDS English paper leans heavily on this format
CUET / CLAT EnglishMedium — grammar questions reuse the same list

Questions aspirants ask

Pulled from the Q&A community and mentor sessions.

2–3 in Tier 1 and 4–6 in Tier 2 directly — but the same 25-rule list also powers Sentence Improvement and grammar-based Fill-in-the-Blanks, so the rule book effectively covers 10–15 questions across the English paper.

Yes. SSC deliberately plants errors that sound natural ('discuss about it', 'since five years', 'one of my friend') and correct constructions that sound stiff ('It being a rainy day…'). Ear-based attempts plateau around 60–70%; rule-based scanning reaches 90%+.

Roughly 15–20% of questions. If two passes of the scanning algorithm (subject–verb → tense markers → pronouns → prepositions → pairs/parallelism) find nothing you can NAME, choose 'No error' without fear.

Subject–verb agreement across an interrupter — 'The quality of the apples were…'. Close behind: 'one of my friend', 'discuss about', 'since + duration', and 'no sooner…when'. These five alone account for a huge share of PYQ errors.

Learn the rules in families (one family per day for a week), then drill 20 PYQs daily, writing the NAME of the broken rule next to each answer. If you can't name the rule, you guessed — review that family. Naming forces the shift from ear to rule.
