Error Spotting & Grammar tests your ability to identify grammatical errors in sentences and choose the correct alternative. In CUET English, this topic consistently appears with 3-5 questions covering subject-verb agreement, tenses, prepositions, articles, conjunctions, and sentence structure.
1. What is Error Spotting & Grammar?
Error Spotting questions present a sentence (or part of a sentence) with a grammatical error. You must identify the error and/or choose the correct version from the options.
- Purpose: To test your knowledge of English grammar rules, sentence structure, and usage.
- Structure: A sentence with a blank or an underlined part, followed by 4 options — one correct and three grammatically incorrect.
- Skills tested:
- Subject-verb agreement
- Tense consistency
- Preposition usage
- Article usage
- Conjunctions and connectors
- Sentence structure and parallelism
Real CUET Example (2024, Q21): ''How _______________ your name?'' → Correct answer: ''do you pronounce'' (testing question formation).
2. Subject-Verb Agreement
Subject-Verb Agreement means the subject and verb must agree in number (singular/plural). This is one of the most frequently tested grammar topics in CUET.
| Rule | Example | Common Error |
|---|---|---|
| Singular subject → Singular verb | ''She plays the violin beautifully.'' | ''She play the violin'' ❌ |
| Plural subject → Plural verb | ''They go to school every day.'' | ''They goes to school'' ❌ |
| Compound subjects with 'and' → Plural verb | ''The teacher and the student are here.'' | ''The teacher and the student is here'' ❌ |
| Subjects with 'each'/'every' → Singular verb | ''Every student has a book.'' | ''Every student have a book'' ❌ |
| Subjects with 'or'/'nor' → Verb agrees with closest subject | ''Neither the teacher nor the students were present.'' | ''Neither the teacher nor the students was present'' ❌ |
CUET Example (2025, Q22): ''Abhijat's spirits ______________ when he learnt that he had won the first prize.'' → Correct answer: ''soared'' (plural subject 'spirits' takes plural verb).
3. Tenses & Tense Consistency
Tense consistency means using the correct tense throughout the sentence/passage. CUET frequently tests tense errors.
| Tense | When to Use | Example |
|---|---|---|
| Simple Present | Habits, facts, general truths | ''She plays with her dog every day.'' |
| Simple Past | Completed past actions | ''She played the violin at the concert.'' |
| Present Perfect | Action started in past, continuing or relevant now | ''She has been playing badminton her whole life.'' |
| Past Perfect | Action completed before another past action | ''She had been playing video games the whole of yesterday.'' |
| Third Conditional | Hypothetical past situations | ''If I had known, I would have visited him.'' |
CUET Example (2024, Q45): ''I didn't know Rahul was in the hospital. If I __________, I would __________ him.'' → Correct answer: ''had known, have visited'' (Third Conditional).
4. Prepositions
Prepositions show the relationship between a noun/pronoun and other words in a sentence. CUET frequently tests correct preposition usage and collocations.
| Preposition | Usage | Example |
|---|---|---|
| By | Mode of transport, deadline | ''Arrived by bus'' / ''Complete by Friday'' |
| Of | Possession, composition | ''Full of mistakes'' / ''A friend of mine'' |
| With | Accompaniment, instrument, feeling | ''Delighted with the present'' / ''Cut with a knife'' |
| In | Location, time (longer periods), success | ''Succeed in getting the job'' / ''In 2024'' |
| To | Direction, recipient | ''Give it to her'' / ''Go to school'' |
CUET Example (2024, Q8): ''Most guests arrived for the concert __________ bus.'' → Correct answer: ''by'' (mode of transport).
5. Articles
Articles ('a', 'an', 'the') are frequently tested in CUET grammar questions. The choice depends on whether the noun is singular/plural, countable/uncountable, and specific/general.
| Article | When to Use | Example |
|---|---|---|
| A | Before consonant sounds (singular, general) | ''She gave a first performance'' |
| An | Before vowel sounds (singular, general) | ''An honest person'' / ''An apple'' |
| The | Specific noun (already mentioned or unique) | ''The sun rises in the east'' |
| No Article | Plural/uncountable general nouns | ''Books are expensive'' / ''Water is life'' |
Common Error: ''She gave the first performance'' when it should be ''a first performance'' (if 'first' is not specific/contextually known).
6. Conjunctions and Connectors
Conjunctions connect words, phrases, or clauses. CUET tests correct conjunction usage based on logical relationships.
| Conjunction | Function | Example |
|---|---|---|
| And | Addition | ''She studied hard and passed the exam.'' |
| But / Yet / However | Contrast | ''He is a miser but he spent lakhs on his daughter's marriage.'' |
| Because / Since / As | Reason | ''He failed because he didn't study.'' |
| So / Therefore / Hence | Result | ''He didn't study, so he failed.'' |
| Although / Though / Despite | Concession | ''Although he was tired, he worked late.'' |
CUET Example (2025, Q35): ''He is a miser _______ he spent lakhs on his daughter's marriage.'' → Correct answer: ''although'' (contrast).
7. Question Formation (Interrogatives)
CUET tests correct question formation — using the right auxiliary verb, word order, and question word.
- Wh-questions: Question word + auxiliary verb + subject + main verb. e.g., ''How do you pronounce your name?''
- Yes/No questions: Auxiliary verb + subject + main verb. e.g., ''Did you complete the report?''
- Common Error: Incorrect word order or missing auxiliary. e.g., ''How you pronounce your name?'' ❌
CUET Example (2025, Q21): ''How _______________ your name?'' → Correct answer: ''do you pronounce'' (Wh-word + auxiliary + subject + main verb).
8. Verb Forms and Usage
CUET tests correct verb forms — ensuring the verb matches the tense, subject, and context.
- Gerund (-ing form): Used after certain verbs (e.g., ''Kalyani made her children do some chores'' — ''do'' not ''doing'').
- Infinitive (to + verb): Used after certain verbs/expressions.
- Modal verbs: ''Can,'' ''could,'' ''would,'' ''should'' — each has specific usage.
CUET Example (2024, Q30): ''Kalyani made her children___________ chores on Sunday.'' → Correct answer: ''do some'' (causative construction: 'made' + object + bare infinitive).
9. Sample Walkthrough (CUET 2024, Q45)
Question: ''I didn't know Rahul was in the hospital. If I __________, I would __________ him.''
Options: (1) knew, go (2) had known, have visited (3) have known, be going (4) know, had gone
Step 1 – Understand the sentence: The speaker didn't know Rahul was in the hospital (past). This is a hypothetical past situation.
Step 2 – Identify the correct conditional: Third Conditional is used for past hypothetical situations — ''If + Past Perfect, would have + Past Participle''.
Step 3 – Check options: Only option (2) fits: ''If I had known, I would have visited him.''
Step 4 – Answer: Option (2) — ''had known, have visited''.
10. Common Traps & How to Avoid Them
- Trap: Subject-Verb Agreement with collective nouns. Collective nouns (team, family, committee) take singular verbs when considered as a unit. e.g., ''The team is ready'' — not ''are''.
- Trap: Subject-Verb Agreement with words like ''each,'' ''every,'' ''anyone''. These always take singular verbs. e.g., ''Each of the students has a book'' — not ''have''.
- Trap: Tense consistency in complex sentences. The tense in the main clause and subordinate clause must make logical sense together.
- Trap: Preposition collocations. Some words always pair with specific prepositions — ''succeed in'' not ''succeed to''; ''full of'' not ''full with''.
- Trap: Article usage with proper nouns and abstract nouns. ''She gave a first performance'' — not ''the first performance'' unless contextually specific.
Common Mistakes
- Subject-verb agreement errors with collective nouns (e.g., ''The team are ready'' instead of ''The team is ready'').
- Subject-verb agreement errors with 'each'/'every' (e.g., ''Every student have'' instead of ''Every student has'').
- Tense inconsistency — mixing past and present tenses without logical reason.
- Incorrect preposition usage — not knowing collocations (e.g., ''succeed to'' instead of ''succeed in'').
- Incorrect article usage — using 'the' when 'a' is required, or vice versa.
- Incorrect question formation — missing auxiliary or incorrect word order.
- Confusing modal verbs — using 'will' instead of 'would' in past/polite contexts.
