Common Grammar Errors in PSLE English Composition—and How to Fix Them
Grammar mistakes are useful evidence.
They show where a student’s language system becomes unreliable: tense, agreement, reference, sentence boundaries, prepositions, articles, modifiers or punctuation. The important question is not simply how many errors appear, but whether the same pattern keeps returning.
Quick Read
- Grammar supports meaning; errors matter most when they distort or weaken communication.
- Repeated errors are more useful diagnostically than isolated slips.
- Knowing a rule on a worksheet does not guarantee accurate use in composition.
- Tense, agreement, pronoun reference and sentence boundaries are common high-value targets.
- Students need correction, explanation, fresh practice and delayed re-testing.
- Proofreading should focus on personal error patterns rather than every possible grammar rule at once.
One-sentence answer: grammar improves most reliably when students identify recurring patterns, understand the underlying rule, practise it in context and then prove they can transfer the repair into new writing.
1. Tense Shifts
Narrative compositions often use past tense, but students may shift accidentally after dialogue, reflection or a flashback.
She opened the door and sees the broken vase.
The useful question is not “Are all verbs past tense?” but “Where does time change, and is that change deliberate?”
2. Subject–Verb Agreement
Agreement errors often appear when the subject and verb are separated.
The basket of books was heavy.
The verb agrees with basket, not the nearer plural noun books.
3. Sentence Fragments
A fragment looks like a sentence but does not stand as a complete independent clause.
Because he had forgotten his keys.
The reader is still waiting for the main clause.
4. Run-On Sentences and Comma Splices
Students sometimes connect complete clauses without enough grammatical structure.
I saw the bus, I started running.
Possible repairs include a full stop, a suitable conjunction or a correctly structured subordinate clause.
5. Pronoun Reference
Mei spoke to Sarah after she left the hall.
Who left?
Grammar is not only agreement and tense. Reference matters because the reader must know what each pronoun points to.
6. Articles
A, an and the can be difficult because their use depends on countability, specificity and whether the receiver already knows which noun is meant.
Article errors are especially common for multilingual learners whose other languages organise definiteness differently.
7. Prepositions and Collocations
Some errors are best learned as word combinations rather than abstract rules.
- interested in;
- responsible for;
- afraid of;
- depend on.
Repeated exposure and retrieval in context are usually more useful than memorising isolated preposition lists.
8. Misplaced Modifiers
A modifier should sit close enough to the word or phrase it modifies.
Running down the corridor, the bag slipped from Jia’s shoulder.
The structure accidentally suggests that the bag was running.
9. Apostrophes
Apostrophes often cause confusion between plural forms, possessives and contractions.
- girls — plural;
- girl’s bag — one girl’s possession;
- girls’ bags — possession belonging to more than one girl;
- it’s — contraction of it is or it has;
- its — possessive.
10. Dialogue Grammar and Punctuation
Dialogue can concentrate several error types in one place: quotation marks, paragraphing, punctuation, tense and speaker reference.
It deserves targeted practice rather than being left to a generic final check.
Knowledge Versus Transfer
A student may answer ten subject–verb agreement questions correctly and still make agreement errors while writing.
This does not necessarily mean the rule was never learned. It may mean the rule is not yet available when attention is divided among ideas, vocabulary, spelling and story structure.
That is why grammar practice must eventually return to authentic writing.
A Better Grammar Repair Cycle
- Identify the repeated error.
- Explain the underlying rule or relationship.
- Correct one example.
- Generate a fresh example.
- Use the structure in a paragraph.
- Re-test days later.
- Check whether it survives inside a full composition.
Build a Personal Error Profile
| Recurring error | Trigger | Checking cue |
|---|---|---|
| Tense shifts | After dialogue | Check first verb after speech |
| Pronoun ambiguity | Several characters in scene | Name the noun again if needed |
| Run-ons | Action scenes | Locate complete clauses |
| Apostrophe confusion | Possession | Ask plural, possessive or contraction? |
| Agreement errors | Long noun phrases | Find true subject |
What Parents Can Do
- Do not correct every error simultaneously.
- Choose one recurring pattern.
- Ask the child to explain the correction.
- Let the child repair it.
- Look for the same pattern in later writing.
This keeps grammar support diagnostic rather than punitive.
How a Three-Student Class Helps
Three students can analyse the same incorrect sentence and propose different repairs. The tutor can then ask which version expresses the intended relationship most clearly.
This moves grammar from “find the error” towards “understand what the sentence is trying to do”.

Frequently Asked Questions
Can a composition still be strong with some grammar errors?
Individual slips can occur in otherwise strong writing. The more important concerns are frequency, severity, whether meaning is affected and whether the same errors recur.
Is learning grammar rules enough?
No. Students must retrieve and apply those rules while performing real reading, speaking and writing tasks.
Grammar Is Control of Relationships
The goal is not a page with no red marks.
It is a writer whose sentences increasingly say exactly what the writer intended.
