📌 1. Approach — a 5-step Checklist
- 1. Subject-verb: is the subject singular or plural? Does the verb match?
- 2. Tense: does the tense fit the time marker (yesterday, since, already)?
- 3. Pronoun: case (I/me), agreement (each…his), clear reference?
- 4. Modifiers: adjective vs adverb, degree of comparison, few/little.
- 5. Fixed pairs & prepositions: no sooner…than, prefer…to, discuss (no about), parallelism.
- If no error is found choose "No error" — but treat it as the last resort.
📌 2. High-frequency Error Rules
| Rule | Wrong | Right |
|---|---|---|
| Each/every/either + singular pronoun | Each student must bring their book. | Each student must bring his or her book. |
| "One" takes one's | One should do his duty. | One should do one's duty. |
| Parallelism | He likes swimming, to read and cycling. | He likes swimming, reading and cycling. |
| Compare like with like | The climate of Shimla is better than Delhi. | …better than that of Delhi. |
| Redundancy | He returned back home. | He returned home. |
| Though…yet (not but) | Though he is poor but he is honest. | Though he is poor, (yet) he is honest. |
| Unless/until are already negative | Unless you do not work hard, you will fail. | Unless you work hard, you will fail. |
| No double negative with scarcely/hardly | I can't hardly hear you. | I can hardly hear you. |
| Superlative + of all; comparative + any other | He is taller than any boy in the class. | …taller than any other boy in the class. |
| Enjoy/avail/absent/pride need a reflexive | We enjoyed at the party. | We enjoyed ourselves at the party. |
⚠️ Exam Traps:
- "Cousin brother/sister" ❌ — just cousin.
- "Kindly revert back" ❌ → "Kindly reply". "Return back", "repeat again", "the reason is because" — redundant.
- "Ought" takes "to": You ought to respect elders.

| principal / principle | principal = chief/head; principle = rule/belief |
