8.4 Error Spotting & Phrase Replacement (Grammar Rules)

8.4 Error Spotting & Phrase Replacement (Grammar Rules)

Error Spotting and Phrase Replacement (Sentence Improvement) constitute fundamental scoring areas in both Prelims and Mains papers for SBI PO. In Error Spotting questions, a sentence is divided into four or five parts (A, B, C, D), and candidates must identify the part containing a grammatical error. In Phrase Replacement questions, a specific section of a sentence is bolded, and candidates must choose the option that grammatically improves the highlighted phrase without altering the intended meaning.

While intuition can solve basic errors, SBI PO questions are intentionally engineered to bypass sound-based reading. Examiners construct complex sentences with embedded clauses to mask structural errors. Relying on concrete, rule-based scanning is essential.

The 10 Golden Grammar Rules for SBI PO

1. Subject-Verb Agreement with Intervening & Parenthetical Phrases

When a subject is separated from its verb by expressions such as along with, together with, as well as, in addition to, accompanied by, or including, the verb agrees strictly with the first subject.

• Incorrect: The Governor of the Reserve Bank of India, along with senior deputy governors, have attended the summit.
• Correct: The Governor of the Reserve Bank of India, along with senior deputy governors, has attended the summit.

2. Proximity Rule for Correlative Conjunctions

When subjects are connected by either...or, neither...nor, or not only...but also, the verb agrees with the subject closest to it.

• Incorrect: Neither the chief executive officer nor the department directors was aware of the audit discrepancy.
• Correct: Neither the chief executive officer nor the department directors were aware of the audit discrepancy.

3. Subject-Verb Inversion after Negative Adverbs

When a sentence or clause begins with a negative or restrictive adverb (such as Hardly, Scarcely, Barely, No sooner, Seldom, Never, Under no circumstances, Little), the auxiliary verb must precede the subject.

• Rule Structure: Negative Adverb + Auxiliary Verb + Subject + Main Verb.
• Incorrect: Hardly the bank had opened its vault when the alarms sounded.
• Correct: Hardly had the bank opened its vault when the alarms sounded.
• Note on No Sooner: No sooner is always followed by than (not when). Hardly/Scarcely is followed by when or before.

4. Parallelism in Correlative & Coordinated Structures

Items in a list or connected by correlative conjunctions (not only...but also, both...and) must share identical grammatical form (nouns paired with nouns, infinitives with infinitives, gerunds with gerunds).

• Incorrect: The new credit policy aims not only at reducing non-performing loans but also to increase farm liquidity.
• Correct: The new credit policy aims not only at reducing non-performing loans but also at increasing farm liquidity.

5. Tense Consistency in Conditional & Past Perfect Clauses

• Past Perfect Sequence: When two actions occurred in the past, the earlier completed action takes the Past Perfect (had + V3), while the subsequent action takes Simple Past (V2).
  • Incorrect: The stock market closed before the regulatory announcement was made public.
  • Correct: The stock market had closed before the regulatory announcement was made public.
• Unreal Present / Subjunctive: Hypothetical conditions take were for all subjects.
  • Correct: If the analyst were (not was) in charge of fiscal policy, she would slash corporate tax rates.

6. The "It is high time" Rule

When the expression It is high time, It is time, or It is about time is followed by a subject, the verb must be in the Simple Past tense (V2) to express present urgency.

• Incorrect: It is high time the board of directors takes corrective action.
• Correct: It is high time the board of directors took corrective action.

7. Dangling and Misplaced Participles

A participial phrase at the start of a sentence must modify the noun immediately following the comma. If that noun cannot logically perform the action of the participle, the modifier is "dangling".

• Incorrect: Walking into the board room, the quarterly audit report was presented to the chairman.
• Correct: Walking into the board room, the chief financial officer presented the quarterly audit report to the chairman.

8. Uncountable Nouns & Pluralization Traps

Certain nouns in banking context are uncountable and cannot take an indefinite article (a/an) or plural suffix (-s): information, advice, equipment, furniture, luggage, machinery, infrastructure.

• Incorrect: The consultant provided several valuable advices regarding currency hedging.
• Correct: The consultant provided several valuable pieces of advice regarding currency hedging.

9. Prepositional Idiom Errors

SBI PO frequently tests unnecessary or erroneous prepositions following transitive verbs:

• Incorrect: The committee will discuss about the bailout package.
• Correct: The committee will discuss the bailout package.
• Incorrect: The board comprises of seven independent directors.
• Correct: The board comprises seven independent directors. (OR: is composed of).

10. Comparative Form & Preposition Selection

Adjectives ending in -ior (superior, inferior, senior, junior, prior) and verbs like prefer are followed by the preposition to, never than.

• Incorrect: Sovereign bonds are preferred than corporate debentures by conservative investors.
• Correct: Sovereign bonds are preferred to corporate debentures by conservative investors.
