1 Quick Introduction

English

Error spotting is the bread-and-butter of every competitive English paper. A sentence is split into parts and you must find the one with a mistake (or mark 'No error'). Speed and accuracy come from a fixed checklist: scan for agreement, tense, pronouns, prepositions, articles and modifiers — in that order — every single time.

हिन्दी

Error spotting हर प्रतियोगी अंग्रेज़ी पेपर का मूल भाग है। एक वाक्य को भागों में बाँटा जाता है और आपको वह भाग ढूँढना है जिसमें गलती हो (या 'No error' चुनना है)। गति और शुद्धता एक निश्चित checklist से आती है: हर बार एक ही क्रम में — agreement, tense, pronouns, prepositions, articles और modifiers — जाँचें।

2 A Real-Life Situation

Imagine this

A typical exam item:

Q: (A) One of the boys / (B) who came late / (C) were punished / (D) by the teacher. / (E) No error

Answer: (C) — 'One of the boys … was punished' (the subject is 'One', singular).

Why this form? The trap is the plural 'boys' just before the verb. Your checklist — 'find the real subject first' — instantly reveals the error in part C. That is how a trained eye scores fast.

3 The Grammar Rule

Rule & Formula
StepCheck
1Read for overall meaning
2Subject-verb agreement
3Tense consistency
4Pronoun usage
5Articles & determiners
6Prepositions
7Adjective/adverb & comparison
8Parallel structure
Run the 8-point checklist on every sentence, in order
Spot the error: 'He is more cleverer than his brother.' → 'more cleverer' (double comparative).

4 The 8-Step Approach

Apply this checklist to every sentence, in order, until you find the error:

  1. Meaning — read the whole sentence first.
  2. Subject-verb agreement — find the real subject (ignore intervening phrases).
  3. Tense — check consistency and sequence.
  4. Pronouns — case (I/me), agreement, clear reference.
  5. Articles & determiners — a/an/the, much/many.
  6. Prepositions — collocations (good at, married to).
  7. Adjectives/adverbs & comparison — degrees, double comparatives.
  8. Parallelism — items in a list/correlative must match.

If none of the eight reveals a mistake, the answer is 'No error' — and about 15–20% of items genuinely have no error, so trust your checklist.

Worked Example
Spot the error: (A) The quality of / (B) the products / (C) are excellent. / (D) No error
Solution

(C) — subject is 'The quality' (singular) → 'is excellent'.

2
Worked Example
Spot the error: (A) He insisted / (B) on to go / (C) with us. / (D) No error
Solution

(B) — 'insist on' + gerund → 'on going'.

Key Points

  • Run the 8 checks in order: meaning, agreement, tense, pronoun, article, preposition, comparison, parallelism
  • Find the real subject — ignore intervening phrases
  • About 15–20% of items are 'No error' — trust the checklist

5 High-Frequency Error Traps

Exam-setters reuse the same traps. Memorise them:

TrapWatch for
Collective nounsThe committee has/have (singular as one unit)
Indefinite pronounsEveryone … his/their (singular, strict)
Either/Neithersingular verb; nor pairs with neither
'The + adjective'The rich are… (plural meaning)
Double comparativesmore better, more superior ✗
Redundancyreturn back, revert back, free gift
Confused wordsaffect/effect, principle/principal
Double negativeshardly … any (not 'no')
Bare infinitivemust to go ✗ → must go
Who vs whomwho = subject; whom = object
1
Worked Example
Spot the error: (A) Hardly had I slept / (B) when there was / (C) no any sound. / (D) No error
Solution

(C) — 'no any' is a double negative; use 'any' after 'hardly' (or 'no sound').

2
Worked Example
Spot the error: (A) The committee / (B) have decided / (C) to postpone it. / (D) No error (acting as one unit)
Solution

(B) — acting as one unit, 'committee' takes 'has decided'.

Key Points

  • Memorise traps: collective nouns, either/neither, double comparatives, redundancy
  • Confused words (affect/effect), double negatives (hardly … any)
  • Modals take the bare infinitive (must go, not must to go)
