Error spotting is one of the most reliable scoring opportunities in IBPS Clerk English. The format is simple: a sentence is split into three or four labelled parts, and your job is to identify which part — if any — contains a grammatical mistake.
Here is the critical insight most test-takers miss: error spotting is not about "sounding wrong." The whole trap is that these sentences are designed to sound perfectly natural when you read them quickly. "She is senior than her colleague" sounds fine to most ears. It isn't. The error is rule-based, not ear-based, which means the moment you learn the specific rules that get tested, this section becomes almost mechanical.
Think of it like a document audit. A bank clerk who processes account opening forms does not guess whether a form is correct — they run through a checklist. KYC present? Signature in the right box? Date format correct? That's exactly how you should approach error spotting. Not gut feeling, not "does it sound okay," but a systematic scan against known rule types.
The rule categories that appear repeatedly in IBPS Clerk are:
each, neither...nor, one of those whodespite of vs despite, senior to vs senior than, look forward to + gerundlay vs lie, laid vs lay, gerund vs infinitivethat with question wordsThe good news is that roughly 70-80% of errors across IBPS Clerk papers fall into these four categories. You do not need to memorise the entire grammar of English — you need to know about fifteen rules extremely well.
This is the single biggest error category in IBPS Clerk. The test-makers know that when a subject looks plural or sounds plural, most candidates reach for a plural verb — even when grammar demands a singular one.
Rule: Each, every, either, neither (used alone) take singular verbs.
Each of the employees was given a bonus. — not were.
The word each is distributive. It treats the group one-by-one. No matter how many employees there are, each sees them individually. Singular verb, always.
Rule: Neither...nor / Either...or — verb agrees with the subject closest to the verb.
Neither the teacher nor the students were present.
Here, students is closest to the verb, and students is plural, so the verb is were. Had it been Neither the students nor the teacher was present, the verb would be was because teacher is closest.
Rule: One of those [noun] who — the relative clause verb agrees with the plural noun, not with one.
She is one of those students who always complete their homework.
Why? Because the relative pronoun who refers back to students (plural), not to one. The verb inside the who-clause must therefore be plural: complete, not completes.
This rule trips up almost everyone who hasn't specifically studied it, because the intuitive (wrong) reading is: "She is one [singular] → she completes." Fight that instinct.
Some adjectives and phrases in English have fixed prepositions — no negotiation, no exceptions.
The Latin-origin comparatives take to, not than.
Words like senior, junior, superior, inferior, prior, anterior, posterior are Latin comparatives. They already carry a comparative meaning built in. You do not add than to them.
She is senior to her colleague.She is senior than her colleague.The trick: if you can substitute the word with older than, the English word takes to, not than.
Despite stands alone — it does not need of.
Despite = In spite of. You cannot have Despite of. Choose one or the other:
Despite the heavy rain, the match continued.In spite of the heavy rain, the match continued.Adding of after despite is the most common preposition error in IBPS papers.
Look forward to takes a gerund (verb + -ing).
To here is a preposition, not part of a to-infinitive. Whenever to functions as a preposition, what follows must be a noun or a gerund, not a bare verb.
I am looking forward to meet you.I am looking forward to meeting you.Other verbs with the same preposition trap: object to, used to (habitual), addicted to, committed to, devoted to — all take gerunds.
Lay vs LieThis pair is consistently misused and consistently tested.
| Verb | Meaning | Present | Past | Past Participle |
|------|---------|---------|------|----------------|
| lie | to recline (intransitive) | lie | lay | lain |
| lay | to place something (transitive) | lay | laid | laid |
The classic trap: He laid down on the bed.
Laid is the past tense of lay (to place something). But you do not place yourself — you recline. So the verb needed is lie, and its past tense is lay.
Correct: He lay down on the bed.
The confusion exists because lay is both the present tense of lay (transitive) and the past tense of lie (intransitive). The only way through is learning the full conjugation table.
When you convert a direct question to indirect speech, the question word (where, when, why, how) acts as a conjunction. You do not add that before it.
He asked, "Where are you going?"He asked me that where I was going.He asked me where I was going.The word that and a question word cannot both be used as connectors in the same clause. One must go.
When you see adjectives ending in -or that come from Latin — senior, junior, superior, inferior, prior — the preposition is always to, never than. Test: cover the adjective, read the sentence with "older/better/worse than." The moment you restore the Latin adjective, swap than to to. Standard method: re-reading the sentence twice to "hear" what sounds right → 20–30 seconds. This pattern check: 3 seconds.
For neither...nor and either...or, draw a quick bracket around the subject nearest the verb. That subject alone determines singular or plural. You don't average them, you don't look at the first subject — only the last one before the verb. Checking both subjects and debating agreement takes 4 steps; checking only the proximate subject takes 1 step.
The moment you see each or every as the subject (or head of the subject phrase), lock in singular verb. Do not look at the noun that follows (each of the employees — ignore employees). Eliminate all plural-verb options immediately. This reduces a 4-option question to a 2-option question in under 2 seconds.
When you see a phrase like look forward to, object to, addicted to — mentally replace to with of. You'd never say "looking forward of meet you." Because of can only precede a noun or gerund, this substitution instantly reveals that the next word must be a gerund. Standard method: recalling whether to is preposition or infinitive-marker → 15 seconds of doubt. Substitution test: 3 seconds, no doubt.
Ask: is there an object after the verb? He lay down — no object, intransitive → lie family. She laid the file on the table — file is the object, transitive → lay family. Two steps, and you never confuse the pair again. Standard method: recalling both conjugation tables → 20+ seconds. This check: 5 seconds.
When you read an error-spotting question in the exam hall, run this checklist in order. Stop the moment you find the error — don't keep reading.
Step 1 — Subject check. Identify the subject. Is it each, every, either, neither used alone? Singular verb mandatory. Is it neither A nor B or either A or B? Check the subject closest to the verb.
Step 2 — Preposition check. Spot any adjective ending in -or (senior, junior, superior, inferior). Its preposition must be to. Spot despite — no of after it. Spot look forward to / object to / addicted to — next word must be a gerund.
Step 3 — Verb form check. Is there a lay/lie usage? Apply the object test. Is there a to + verb after a preposition? Convert to gerund.
Step 4 — Indirect speech check. Does the sentence report a question? Look for that before a question word — delete that if found.
Step 5 — If none of the above triggered, choose "No error" — but do this only after genuinely running the checklist, not as a default guess.
Total time budget per question: 30–45 seconds. If you've run the checklist and found nothing in 45 seconds, mark "No error" and move on.
Why this question: Tests the look forward to + gerund rule — the single most frequently tested preposition-gerund trap in IBPS English.
Solving path: Part B reads to meet you. The phrase looking forward to — here, to is a preposition (not part of an infinitive). A preposition must be followed by a noun or gerund. Meet is a bare infinitive. Change it to meeting. Part B is the error. Done in under 15 seconds once you know the rule.
Why this question: Tests the proximity rule for neither...nor — a rule that looks counterintuitive because the eye is drawn to the first, not the last, subject.
Solving path: Identify the neither...nor structure. The two subjects are teacher (singular) and students (plural). The subject closest to the verb is students — plural. The verb must be were, not was. Part B contains was — that's the error.
Why this question: Tests the Latin comparative + preposition rule. Most candidates guess "No error" because the sentence sounds natural.
Solving path: Part A contains senior than. Senior ends in -or and is a Latin comparative — it must take to, not than. Replace than with to. Part A is the error. If you've memorised the LESS pattern (Latin, End in -or, Senior/Superior → to), this takes 5 seconds.
Why this question: Tests the one of those who rule — among the most commonly misapplied agreement rules at this level.
Solving path: The structure is one of those students who [verb]. The who refers back to students (plural), not to one (singular). The verb in the relative clause must be plural: complete, not completes. Part B contains completes — error identified.
Why this question: Tests lay/lie confusion — a grammatical trap that even fluent speakers fall into because both forms look plausible.
Solving path: Part A says He laid down on the bed. Apply the object test: is there an object after the verb? He laid down — no object. This must be the intransitive verb lie (to recline). Past tense of lie is lay. So the correct form is He lay down on the bed. Part A is the error.
Why this question: Tests each + singular verb. Very frequently paired with a plural noun in the of-phrase to create the illusion that a plural verb is needed.
Solving path: Subject is Each of the employees. Each is distributive and always singular. Ignore employees. The verb must be was, not were. Part B contains were — that's the error.
Why this question: Tests indirect speech construction with question words — a rule that many candidates have never explicitly studied.
Solving path: Part B reads that where I was going. In indirect speech, when a question word (where, when, why) is already acting as the connector, that is redundant and grammatically wrong. Remove that. The correct form is He asked me where I was going. Part B is the error.
Why this question: Tests the despite vs despite of distinction — the single most common preposition error at IBPS Clerk level.
Solving path: Part A reads Despite of the heavy rain. Despite does not take of. It is either Despite the heavy rain or In spite of the heavy rain — never Despite of. Part A is the error. This should take under 10 seconds once the rule is fixed.
Defaulting to "No error" when confused. "No error" is a valid answer, but it is also the lazy answer. Run the full checklist before choosing it. In IBPS Clerk papers, "No error" is not the majority answer.
Relying on what "sounds right." The sentences are constructed precisely because incorrect forms sound acceptable. She is senior than her colleague passes the ear test for most readers. Rules override instinct here.
Ignoring the part boundaries. Some errors span two parts — for example, a subject in Part A and a wrong verb in Part B. The error is credited to the part containing the wrong word, not the part containing the subject that caused the wrong choice. Always identify the wrong word first, then assign the part.
Misidentifying the subject in each of / one of phrases. Candidates see each of the employees and parse employees as the subject. The subject is each. The of-phrase is a modifier. Cover the of-phrase when identifying the subject.
Confusing lay (past of lie) with laid (past of lay) without checking transitivity. The forms overlap in spelling, which is the entire trap. Always apply the object test before choosing the verb form.
Using both that and a question word in indirect speech. This is a direct translation error from Hindi sentence structure where कि (ki) functions like that. English does not allow that + where/when/why/how in the same clause. One must be dropped, and it is always that that goes.
