3.4 Common Grammar & Usage Errors
Key Takeaways
- Pronouns must agree with their antecedents in number and refer clearly to one noun; vague or mismatched pronouns are frequent MCQ traps.
- Dangling and misplaced modifiers attach the wrong description to the wrong noun—repair by placing the modifier next to the word it truly describes.
- Double negatives, non-parallel lists, and wrong prepositions are classic usage errors on civil-service English papers.
- Comma splices, run-ons, and fragment repairs connect this section to sentence structure from 3.1.
- Choose answers by applying a named rule (agreement, parallelism, modifier placement), not by what “sounds smoother” in casual speech alone.
3.4 Common Grammar & Usage Errors
Quick Answer: Entrance-style English papers recycle a short list of usage faults: pronoun agreement and reference, dangling or misplaced modifiers, double negatives, wrong prepositions, faulty parallelism, and comparison errors. Learn the rule, then pick the option that obeys it in formal standard English.
Sections 3.1–3.3 gave you structure, agreement, and tense. This section targets the mixed “identify the error / choose the correct sentence” items that combine those skills with everyday usage.
How Error-Identification Items Work
Typical formats:
- Four full sentences — choose the grammatically correct one.
- Four full sentences — choose the incorrect one.
- One sentence with underlined parts — choose the underlined error (or “no error”).
- A sentence with a blank — choose the word or phrase that fits formal usage.
Work methodically: check subject–verb pair, then pronouns, then modifiers, then parallel lists, then negatives and prepositions.
Pronoun Agreement
A pronoun must agree with its antecedent (the noun it replaces) in number (and, where relevant, person).
| Antecedent | Pronoun |
|---|---|
| singular noun (candidate, notice, commission) | he/she/it, him/her/it, his/her/its |
| plural noun (candidates, notices) | they, them, their |
| each, everyone, everybody, anyone, nobody | traditionally singular (his or her, he or she; exam keys often avoid plural they for these) |
| who | people |
| which | things (non-restrictive often); that for restrictive things/people in many school keys |
Examples:
- Every candidate must bring his or her identification. (formal exam style)
- All candidates must bring their identification.
- The committee has issued its decision. (committee as unit)
Faulty:
Everyone submitted their forms early. — Many modern speakers accept this; traditional MCQ keys may still prefer singular agreement or a rewrite to All candidates submitted their forms.
Strategy: If options include a clean plural rewrite (All applicants… their…) or his or her, prefer the option that matches the paper’s traditional formal standard without awkwardness.
Pronoun Reference (Clarity)
Even when number is right, the pronoun must point to one clear noun.
Unclear:
When the clerk spoke to the applicant, she was annoyed. (Who was annoyed?)
Clear:
When the clerk spoke to the applicant, the applicant was annoyed.
Or: The applicant was annoyed when the clerk spoke to her.
Unclear this/that/which:
The portal closed at noon, which caused confusion. (Acceptable if which clearly means the closing; weak if many ideas precede it.)
Prefer:
The portal’s noon closing caused confusion.
Wrong case:
| Function | Correct forms |
|---|---|
| Subject | I, he, she, we, they, who |
| Object | me, him, her, us, them, whom |
| Possessive determiner | my, his, her, our, their, whose |
| Possessive pronoun | mine, his, hers, ours, theirs |
- The letter was addressed to him and me (not I).
- Who submitted the form? / To whom was the letter sent? (formal)
- Between you and me (not I).
Dangling and Misplaced Modifiers
A modifier is a word or phrase that describes another word. It should sit next to (or clearly attach to) what it describes.
Dangling modifier
The introductory phrase has nothing logical to describe in the main clause.
Dangling:
Having completed the form, the stamp was applied.
(The stamp did not complete the form.)
Repair:
Having completed the form, the clerk applied the stamp.
Or: After the form was completed, the stamp was applied.
Dangling:
To qualify for the post, the age requirement must be met.
Repair:
To qualify for the post, applicants must meet the age requirement.
Misplaced modifier
The phrase is in the sentence but next to the wrong word.
Misplaced:
The officer almost checked all the files. vs The officer checked almost all the files. (meaning changes)
Misplaced:
Candidates were told on Monday to collect letters. (clear)
Candidates were told to collect letters that were printed on Monday. (different meaning — letters printed Monday)
Misplaced:
She handed envelopes to the applicants in plastic covers. (Are the applicants in plastic covers?)
Repair: She handed the applicants the envelopes in plastic covers.
Squinting modifier
A modifier between two phrases that could look either way:
- Officers who work quickly process appeals. vs Officers who work process appeals quickly — place quickly where only one reading works.
Double Negatives
In standard formal English, two negatives in one clause cancel or are non-standard.
| Non-standard / faulty on exams | Standard |
|---|---|
| Candidates did not bring no documents. | Candidates did not bring any documents. |
| She can’t hardly wait. | She can hardly wait. / She can’t wait. |
| There isn’t nobody outside. | There isn’t anybody outside. / There is nobody outside. |
Negative words and ideas: no, not, never, none, nothing, nobody, neither, hardly, scarcely, barely, without.
Hardly/scarcely/barely already carry negative force — do not add not.
Parallel Structure
When you list or compare, use the same grammatical form for each element.
| Faulty | Parallel |
|---|---|
| The role requires honesty, fitness, and to be punctual. | The role requires honesty, fitness, and punctuality. |
| She likes reviewing files, to interview applicants, and reports. | She likes reviewing files, interviewing applicants, and writing reports. |
| The notice was clear, concise, and it helped candidates. | The notice was clear, concise, and helpful. |
Correlative pairs must stay balanced:
- both … and …
- either … or …
- neither … nor …
- not only … but also …
- whether … or …
Faulty: The form is not only long but also it is confusing.
Parallel: The form is not only long but also confusing.
Faulty: Either candidates may apply online or by post.
Parallel: Candidates may apply either online or by post.
Preposition Choice (High-Frequency Pairs)
Prepositions are often idiomatic. Memorise common formal collocations:
| Prefer | Example |
|---|---|
| apply for a post / apply to an organisation | apply for the vacancy; apply to the Commission |
| responsible for | responsible for the register |
| interested in | interested in public service |
| different from (exam favourite over different than) | different from last year’s form |
| prefer … to … | prefer paper copies to scans |
| between (two) / among (more than two) | between Trinidad and Tobago; among several centres |
| at a time / on a date / in a month or year | at 9:00 a.m.; on Monday; in August |
| good at | good at mathematics |
| comply with | comply with the instructions |
| consistent with | consistent with the circular |
| on the website / in the newspaper | published on the website |
| arrive at a place / arrive in a city/country | arrive at the hall; arrive in Port of Spain |
Wrong: discuss about the issue → discuss the issue.
Wrong: comprise of three parts → comprise three parts / consist of three parts.
Comparisons
- Use comparative (better, more careful) for two; superlative (best, most careful) for three or more.
- Complete the comparison: She is taller than her brother (not She is taller).
- Compare like with like: The salary of a clerk is lower than that of a supervisor (not lower than a supervisor if you mean salaries).
- Avoid double comparison: more better → better; most tallest → tallest.
Adjective vs Adverb
- Adjectives modify nouns: a careful officer.
- Adverbs modify verbs, adjectives, or adverbs: the officer checked carefully.
Faulty: She speaks good. → She speaks well.
Faulty: The form looks well. (if appearance is meant) → The form looks good. (look as linking verb takes adjective)
Linking verbs (be, seem, appear, look, feel, become) often take adjectives as complements: The instructions seem clear.
Fewer vs Less, Number vs Amount
| Use | With |
|---|---|
| fewer, number, many | countable plurals (fewer errors, number of forms) |
| less, amount, much | uncountables (less time, amount of information) |
Exam English still rewards fewer candidates rather than less candidates.
Redundancy and Double Subjects
- Advance planning → planning (planning is already advance).
- Past history → history.
- Each applicants they must… → delete the double subject they.
Connecting Back to Sentence Faults
| Fault | Quick fix |
|---|---|
| Fragment | Add missing subject/verb or attach dependent clause |
| Comma splice | Period, semicolon, or comma + FANBOYS |
| Fused run-on | Same repairs |
| Faulty who/whom | Subject who; object whom |
| Its/it’s | its = possessive; it’s = it is / it has |
| Their/there/they’re | possessive / place or expletive / they are |
| Your/you’re | possessive / you are |
| Affect/effect | affect (usually verb); effect (usually noun) |

Exam-Day Checklist (60 Seconds)
- Subject and verb agree?
- Pronoun has a clear, matching antecedent?
- Introductory -ing/-ed/to-phrase matches the subject that follows?
- Lists and not only…but also structures parallel?
- Only one negative where standard English wants one?
- Preposition matches the collocation table?
- Tense consistent with time words?
Study Routine
- Keep an error log with seven columns: agreement, pronoun, modifier, negative, parallel, preposition, other — file every missed practice item.
- Rewrite five dangling sentences from news headlines into correct public-notice style.
- Build ten parallel lists using not only…but also and either…or.
- Drill its/it’s, their/there/they’re, and affect/effect until recognition is automatic under time pressure.
Usage items reward calm rule application. If two options both look polished, find the named fault in one of them; the correct choice is the sentence that breaks none of the rules in this chapter.
Which sentence avoids a dangling modifier?
Choose the sentence with correct parallel structure.
Which sentence follows standard formal English without a double negative?
