English Language – Error Spotting
(NDA Program – Study Notes)
1. Simple Explanation
Error spotting is the skill of reading a sentence or a paragraph and finding mistakes.
- Mistakes can be in grammar, punctuation, spelling, word choice, or sentence structure.
- Practicing error spotting helps you write clearer, more accurate, and more professional texts.
2. Key Points
| Category | What to Look For | Common Example | Quick Fix |
|---|---|---|---|
| Grammar | Subject‑verb agreement, tense consistency, pronoun‑antecedent agreement | “The group of students was excited.” | “were” (because “group” is singular, but the verb must agree with the collective noun “students” in US English) |
| Punctuation | Commas, semicolons, apostrophes, quotation marks | “She said I love you.” | “She said, “I love you.” |
| Spelling | Misspelled words, homophones | “Their going to the park.” | “They’re” |
| Word Choice | Incorrect collocations, vague words, redundancy | “He gave a very unique idea.” | “He gave a unique idea.” |
| Sentence Structure | Run‑on sentences, fragments, sentence fragments | “When I went to school I saw a dog.” | “When I went to school, I saw a dog.” |
| Capitalisation | Proper nouns, start of sentences | “i visited london last summer.” | “I visited London last summer.” |
| Consistency | Number format, abbreviations, style | “He earned 5,000 dollars.” vs “5,000$” | Pick one style and use it consistently |
Strategy Checklist
- Read aloud – pauses often reveal missing commas or awkward phrasing.
- Break the sentence into clauses – ensure each clause has a subject and a verb.
- Check tense flow – make sure past actions stay in past tense.
- Verify subject‑verb number – singular subjects need singular verbs.
- Look for homophone traps – there/they’re/they’re.
- Confirm punctuation marks – commas after introductory phrases, correct use of apostrophes.
- Use a spell‑checker but don’t rely on it – it misses grammar errors.
3. Worked Example
Original Text (with errors)
He go to the store yesterday, and they had many of the items, so he buy them.
When he was returning, he found that his wallet was missing.
i hope this helps.
Step‑by‑Step Spotting & Correcting
| Line | Error Type | Correction | Explanation |
|---|---|---|---|
| 1 | Verb tense | “He went to the store yesterday” | Past tense of go is went. |
| 1 | Comma splice | Add comma after “yesterday” | Separate two independent clauses. |
| 1 | Subject‑verb agreement | “they had many of the items, so he bought them.” | Past tense of buy is bought. |
| 2 | Capitalisation | “When he was returning, he found that his wallet was missing.” | “His” should be capitalised at the start of a sentence. |
| 3 | Capitalisation | “I hope this helps.” | First person pronoun must be capitalised. |
| 3 | Punctuation | Add period after “helps.” | Ends the sentence. |
Corrected Text
He went to the store yesterday, and they had many of the items, so he bought them.
When he was returning, he found that his wallet was missing.
I hope this helps.
4. Quick Revision Summary
- Grammar: Keep tense consistent; match singular/plural subjects with verbs.
- Punctuation: Use commas after introductory phrases; apostrophes for possession; quotation marks for direct speech.
- Spelling: Watch homophones; use spell‑check as a second line of defense.
- Word Choice: Avoid redundancy; choose precise words.
- Sentence Structure: No fragments or run‑ons; each clause needs a subject + verb.
- Capitalisation: Proper nouns and sentence starts must be capitalised.
- Consistency: Stick to one style for numbers, abbreviations, and formatting.
- Strategy: Read aloud, break into clauses, double‑check tense, and use a checklist when editing.
Practice Exercise
Take a paragraph from a news article or a textbook. Highlight every error you find, then rewrite the paragraph correctly. Compare your version with a peer’s version to see if you missed anything.
Good luck and happy error spotting!
