Error spotting in SBI PO is not just a grammar test — it is a reasoning test dressed in an English costume. You are not being asked whether you "feel" that a sentence sounds off. You are being asked to identify a specific, classifiable error in a specific underlined portion.
Think of a sentence as a machine with four or five interlocked gears (each labeled A, B, C, D). The machine is broken. Your job is not to describe the noise — it is to name which gear is stripped.
Here is where SBI PO diverges from simpler exams: the errors are not always grammar-mechanical. Some sentences are grammatically clean but logically broken — the wrong word is sitting in the wrong slot. "Citizens facing prosperity" do not need a speech on economic resilience. The sentence runs smooth on paper, but the meaning is inside-out. SBI PO setters love this trap because it weeds out candidates who read on autopilot.
The categories you will actually see on the exam:
refuse to accept, not refuse accepting)to not make instead of not to makehelps improving instead of helps improveThe analogy that sticks: imagine a typed letter where the secretary accidentally swapped two words between paragraphs. The font, spacing, and punctuation look fine — but the meaning is ruined. Your eye has to slow down enough to read for sense, not just structure.
These are the "free marks" — if you spot them. The trick is that the misspelling is usually subtle: one extra letter, a transposition, or a doubled consonant where there should be one (accustomned vs. accustomed). Train yourself to read Part (a) or Part (b) letter-by-letter when the sentence has no obvious grammar issue.
This is a high-frequency trap in SBI PO. Certain verbs in English insist on the infinitive (to + base verb) after them, while others take the gerund (verb + -ing). The exam targets the verbs that take only the infinitive:
He refused to accept ✓ | He refused accepting ✗Then there are verbs that take only the gerund:
She enjoys reading ✓ | She enjoys to read ✗And the most examined group: verbs that change meaning depending on which form follows:
| Verb | + Infinitive | + Gerund | |------|-------------|---------| | stop | stopped to rest (paused in order to rest) | stopped resting (ceased resting) | | remember | remember to call (don't forget to call) | remember calling (recall that you called) | | try | try to open (attempt) | try opening (experiment with) |
When you see helps in a sentence, note: helps + base verb is the standard form. Helps improving is wrong; helps improve is correct.
Look — the rule is simpler than it appears. If the main time-frame of the sentence is past, every subordinate clause must also operate in the past unless there is a reason for an exception (universal truths, quoted speech, etc.).
While she was cooking / her children plays / in the garden — the first clause is past continuous (was cooking), so the second clause cannot be present simple (plays). It must be played.
The pattern to watch: when a sentence has a time clause starting with while, when, as, after, before, check that both sides of the conjunction respect the same temporal frame.
The rule in formal grammar is that not should precede to, not sit between to and the verb.
to not make ✗ → not to make ✓to never say ✗ → never to say ✓This rule is contested in modern descriptive grammar, but SBI PO follows the prescriptive tradition — so on the exam, the split infinitive is always the error.
This is where SBI PO shows its fangs. The setters take a sentence, pick two words that have plausible-sounding but contextually wrong positions, and swap them. Your job is to identify which pair has been swapped.
The method:
Example: astute strategies and succumbed to economic prudence — once you restore astute to (C) and succumbed to (A), the sentence works. The tell is that strategies needs a positive adjective (astute), and succumbed to needs to describe others' defeat, not the CEO's advantage.
Closely related to word-swap, but here the mismatch is between a word and its surrounding context — not a swap, but a wrong choice. Citizens facing prosperity is incoherent because prosperity is a positive condition; it does not generate the kind of struggle that calls for a resilience speech. Audacious exhibition + subtle in theme + profound critique of conformity — once you swap conformity and profound, the noun phrase a profound critique of conformity is a standard art-world expression, which fits.
Run the VEST sequence on every error-spotting sentence before choosing an answer: V = Verb form (gerund vs. infinitive, tense agreement) E = Expression (is the word-choice logical in context — word swap?) S = Spelling (read the suspect part letter-by-letter) T = Tense (is every verb in the correct temporal frame?)
Standard approach: read once, hope something jumps out — often takes 60-90 seconds with misses. VEST check: four focused scans, each under 10 seconds = under 50 seconds total with higher accuracy. You save 15-40 seconds per question.
Memorize two short blacklists and burn them in:
Infinitive-only after: refuse, want, decide, agree, plan, hope, manage, fail, arrange, afford, pretend, promise, offer, dare, claim
Gerund-only after: enjoy, avoid, consider, finish, deny, suggest, recommend, keep, mind, risk, practise, postpone, admit, delay
When you see any of these verbs in a sentence, immediately look at what follows. If it violates the list, you have found the error.
Standard approach: re-read the sentence 2-3 times trying to "feel" the wrongness — 30-45 seconds. Blacklist flash: 1 look at the verb + 1 look at what follows = under 10 seconds.
For word-swap questions, do not try all four pair options. Start with the pair that involves a word clearly mismatched with its neighbor.
Rule: adjectives need compatible nouns; verbs need compatible subjects. If you see an adjective sitting next to a noun it would never describe in normal usage, that adjective has been swapped.
succumbed strategies — no one describes a strategy as "succumbed." That mismatch tells you (A) is the displaced word. Find the word that would fit there (astute), confirm the swap.
Standard approach: mentally test all four swap options — 70-80 seconds. Mismatch-first approach: isolate the impossible pairing, confirm one swap — under 25 seconds.
Draw a mental bracket around all verbs in a sentence and label each one: past, present, or future. If any verb breaks the dominant pattern without a grammatical justification (universal truth, reported speech, conditional), it is the error.
Sentence: While she was cooking [past continuous] / her children plays [present simple] — the bracket is broken. One verb is past, one is present. The error is plays.
This reduces tense questions from a holistic re-read to a targeted scan of verb labels. Step count: full re-read method = 4-5 passes. Bracket method = 1 verb-identification pass + 1 comparison = 2 steps.
Train your eye to flag the sequence to + adverb + verb as an automatic alarm — to not make, to never say, to quickly finish. In SBI PO's prescriptive framework, not or any adverb sitting between to and the main verb is always wrong.
The fix is mechanical: move the adverb before to. No analysis needed.
Standard approach: re-read for naturalness — 20-30 seconds. Pattern alarm: spot the to + adverb + verb sequence = under 5 seconds.
When you open an error-spotting question in the exam hall, use this decision tree — do not deviate from it.
Step 1 — Read for meaning (8 seconds). Does the sentence make logical sense in the real world? If not, this is likely a word-swap or logical coherence question. Go to Step 2A.
Step 2A (Word-swap). Identify the word most incongruous with its immediate neighbor. Find its natural partner elsewhere in the sentence. Mentally swap. If the sentence now makes sense, confirm — that is your answer.
Step 2B (Grammatical error). Run VEST: Verb form → Expression → Spelling → Tense. Stop at the first hit.
Step 3 — Eliminate before you commit. If you have two candidate answers, eliminate the one where the rest of the sentence would still be broken even after the fix. The correct answer must make the entire sentence clean.
Step 4 — Do not over-read. Once you find one clear error and the fix makes the full sentence coherent, mark it and move on. SBI PO sentences contain exactly one error per question — do not invent a second one.
Budget: 45-60 seconds per question maximum.
Why this question: This is a classic logical coherence / word-swap question. The grammar is technically fine, but the sentence describes citizens facing prosperity needing a speech on economic resilience — an inside-out relationship.
Solving path: Read for meaning first. Economic resilience + citizens facing prosperity is contradictory — resilience speeches address hardship, not prosperity. Swap B and D: speech on prosperity and citizens facing years of resilience? No, that's still odd. The correct swap is: Part B becomes economic prosperity and Part D becomes years of resilience — meaning citizens who had faced years of hardship (resilience-testing times). This resolves the logical contradiction. Answer: B-D.
Why this question: Tests word-swap where the displaced adjective (astute) ends up far from its natural noun (strategies), and a verb (succumbed) ends up in a position where it describes the CEO's action rather than competitors'.
Solving path: CEO's succumbed strategies — succumbed is a verb meaning yielded/gave in; it cannot function as an adjective modifying strategies. That is the impossible pairing. The word that belongs there is astute. Now check Part C: others astute to economic prudence — astute to is not a standard construction. Succumbed to is. Swap A and C: astute strategies (C becomes a modifier correctly placed) and others succumbed to (A now holds the correct verb phrase). Answer: A-C.
Why this question: Another word-swap where a misplaced adjective (profound) and a misplaced noun (conformity) break both grammar and meaning.
Solving path: a conformity critique of profound — this is syntactically broken. Critique of profound has an adjective where a noun is required. A profound critique of conformity is the standard expression (common in art criticism). Swap C (conformity) and D (profound): the sentence becomes offered a profound critique of conformity. Answer: C-D.
Why this question: A pure spelling error question — no grammatical trap, just a misspelled word hidden in a structurally clean sentence.
Solving path: Scan each part for grammar first — all four are structurally sound. Switch to spelling scan. Part (b): accustomned — standard word is accustomed. The extra n before the e is the error. None of the other parts have spelling issues. Answer: accustomned to waking up early.
Why this question: A direct gerund-vs-infinitive trap after refused. High frequency in SBI PO.
Solving path: refused is on the infinitive-only list. What follows it? accepting the invitation — a gerund phrase. This violates the rule. Correct form: refused to accept the invitation. The error is in Part (b). Answer: accepting the invitation.
Why this question: Split infinitive — to not make — a prescriptive grammar rule that SBI PO tests directly.
Solving path: Trigger the split-infinitive alarm on Part (b): to not make = to + adverb + verb. In prescriptive grammar, not must precede to: not to make. The rest of the sentence is clean. Answer: to not make.
Why this question: Tense inconsistency — past continuous in one clause, present simple in the parallel clause.
Solving path: Apply the Tense-Bracket method. Clause 1: was cooking = past continuous. Clause 2: plays = present simple. Mismatch. The time context is clearly past (an ongoing situation at a past moment). plays must become played. Answer: her children plays.
Why this question: Helps + gerund is a frequent SBI PO trap. The correct construction is helps + base verb.
Solving path: VEST check — Verb form first. Part C: improving concentration. The governing verb is helps in Part B. Rule: helps is followed by the base form of the verb. Improving is a gerund. Correct form: helps improve concentration. Answer: C.
Marking "no error" when the error is semantic, not grammatical. Sentences with word-swaps often read grammatically clean. If you only check grammar and stop there, you will miss the logical incoherence entirely. Always read for meaning before you read for structure.
Confusing "refuses accepting" with a style choice. It is not a style choice — refuse categorically takes the infinitive in standard grammar. Treating verb-form rules as optional leads to consistent losses on a question type that is otherwise free marks.
Correcting the split infinitive in the wrong direction. to not make → to make not is wrong. to not make → not to make is correct. The adverb always moves before to, not after the main verb.
Missing the spelling error because you read words as shapes, not letters. Your brain pattern-matches familiar words and auto-corrects accustomned to accustomed before it registers the error. When a sentence has no obvious grammatical problem, slow down and read each part letter-by-letter.
Trying to swap all four pair-options in word-swap questions. This burns 90+ seconds. Find the one word that cannot plausibly combine with its immediate neighbor — that is your anchor. You only need to test the one swap that restores that word to its logical partner.
Over-correcting tense errors. In the while she was cooking / children plays example, some candidates mark Part (c) or Part (d) as the error because they misread the tense frame. Lock in the dominant tense from the time-clause first, then scan each verb against it.
