Tamil Nadu PSC – English Language
Topic: Error Spotting
The error spotting section tests your ability to detect and correct mistakes in grammar, punctuation, spelling, and usage.
Goal: Identify the wrong part, explain why it’s wrong, and give the correct form.
1. Simple Explanation
| What is it? | Why it matters? |
|---|---|
| Error spotting is a set of questions where you read a sentence (or a short paragraph) and point out the mistake(s). | In the PSC exam accuracy is key. A single wrong mark can cost you the answer. |
| You must not change the meaning of the original sentence. | The examiners check for correctness, not for rewriting. |
2. Key Points to Remember
| Category | Typical Errors | How to Spot |
|---|---|---|
| Grammar | • Subject‑verb agreement (singular/plural) • Tense consistency • Pronoun‑antecedent agreement |
• Look for mismatch between subject and verb. • Check if all verbs in a sentence are in the same tense. • Verify that pronouns match the noun they refer to. |
| Punctuation | • Missing commas before however, therefore, moreover (etc.) • Confusing “its/it’s” • Misplaced apostrophes |
• Read the sentence aloud – does it sound like a pause? • Identify possessive vs. contraction. |
| Spelling | • Homophone confusion (“their/there/they’re”) • Common misspellings (“definitely” vs. “defiantly”) |
• Check the word’s meaning. |
| Usage | • Wrong prepositions (“interested in” vs. “interested on”) • Wrong articles (“a” vs. “an”) |
• Ask: “Which word fits logically?” |
| Word Choice | • “Their” vs. “There” vs. “They’re” • “Effect” vs. “Affect” |
• Identify the part of speech needed. |
3. Worked Example
Paragraph:
The committee, along with the members, have decided to implement a new policy. The policy will helps to improve efficiency in the office. Its aim is to reduce unnecessary delays. Therefore, all employees are required to follow the new guidelines.Task: Spot all errors and correct them.
Step‑by‑Step Analysis
| # | Sentence | Error(s) | Explanation | Corrected |
|---|---|---|---|---|
| 1 | The committee, along with the members, have decided to implement a new policy. | have – subject committee is singular. | “Committee” is a collective noun treated as singular. | has |
| 2 | The policy will helps to improve efficiency in the office. | helps – auxiliary will + simple verb → will help. | “Will” already conveys future tense; the main verb must be base form. | help |
| 3 | Its aim is to reduce unnecessary delays. | Its – should be It’s because it is a contraction of It is. | The sentence means “It is the aim…”. | It’s |
| 4 | Therefore, all employees are required to follow the new guidelines. | No error. | The sentence is grammatically correct. | – |

Final Tips for the Exam

- Keep a Mini‑Word‑Bank – Write down the most common error patterns (e.g., its/it’s, their/there/they’re, is/are).
- Time Management – Spend ~30 seconds per sentence. If you’re unsure, mark and move on; you can return if time permits.
- Practice Regularly – Use past PSC papers or online error‑spotting quizzes.
Good luck, and remember: accuracy beats speed in error spotting!
