Why Possessives Cost You Marks
Possessive errors are one of the top 5 grammar mistakes I see in SPM essays. After marking thousands of essays over 8 years, I can tell you: examiners notice every misplaced apostrophe.
The good news? Possessive rules are simple once you understand them. Most students just never learned them properly.
Apostrophe-S Rules: The Basics
Singular Nouns: Add ‘s
To show that one person or thing owns something, add ‘s (apostrophe + s):
- The student’s book (the book belongs to one student)
- My mother’s cooking (the cooking of my mother)
- The teacher’s desk (the desk belongs to one teacher)
Plural Nouns Ending in S: Add Only ’
When the noun is plural and already ends in s, add only an apostrophe:
- The students’ books (the books belong to multiple students)
- My parents’ house (the house belongs to both parents)
- The teachers’ meeting (the meeting for multiple teachers)
Plural Nouns Not Ending in S: Add ‘s
Some plural nouns don’t end in s (children, men, women, people). Treat them like singular nouns:
- The children’s playground
- The men’s room
- The women’s team
- The people’s choice
Names Ending in S
This is where students get confused. For names ending in s, both forms are acceptable in SPM:
- James’s car OR James’ car
- Charles’s book OR Charles’ book
Pick one style and be consistent throughout your essay.
Its vs It’s: The Most Common Mistake
This single error appears in nearly every batch of SPM essays I mark. Here’s the rule:
It’s = It is (or It has)
It’s is a contraction (shortened form):
- It’s raining. (It is raining.)
- It’s been a long day. (It has been a long day.)
Its = Belonging to it
Its (no apostrophe) is the possessive form:
- The cat licked its paws. (The paws belonging to the cat.)
- The school changed its rules. (The rules belonging to the school.)
The Quick Test
Replace the word with “it is.” If the sentence still makes sense, use it’s. If not, use its.
- “The dog wagged ___ tail.” → “The dog wagged it is tail.” (Doesn’t make sense → its)
- ”___ going to rain.” → “It is going to rain.” (Makes sense → it’s)
Possessive Pronouns: No Apostrophes
Possessive pronouns never take apostrophes. This is a rule many students break:
| Possessive Adjective | Possessive Pronoun |
|---|---|
| my | mine |
| your | yours |
| his | his |
| her | hers |
| its | (not commonly used) |
| our | ours |
| their | theirs |
Common errors to avoid:
your’s→ yoursher’s→ herstheir’s→ theirsour’s→ ours
Examples in Sentences
- “This book is mine.” (NOT
mine’s) - “Is this pencil yours?” (NOT
your’s) - “The idea was theirs.” (NOT
their’s)
Their, They’re, There
Another set that SPM students commonly confuse:
- Their = belonging to them (“Their house is big.”)
- They’re = they are (“They’re coming tomorrow.”)
- There = a place, or used to introduce something (“Put it there.” / “There are three reasons.”)
Quick Test
- Replace with “they are.” If it works → they’re
- If it shows ownership → their
- Everything else → there
Your vs You’re
- Your = belonging to you (“Your essay is good.”)
- You’re = you are (“You’re improving quickly.”)
Quick Test
Replace with “you are.” If it works → you’re. If not → your.
Common SPM Mistakes with Possessives
Mistake 1: Adding Apostrophes to Plurals
Apostrophes show possession, NOT plurals:
The student’s are studying→ The students are studyingI bought two book’s→ I bought two booksMany school’s in Malaysia→ Many schools in Malaysia
Mistake 2: Forgetting the Apostrophe
When you mean possession, the apostrophe is required:
The teacher desk→ The teacher’s deskMy friend house→ My friend’s house
Mistake 3: Wrong Placement
The boy’s are playing(apostrophe makes this possessive, not plural)- The boys are playing (plural, no apostrophe)
- The boy’s ball (possessive, apostrophe needed)
Mistake 4: Double Possessives
Don’t use both an apostrophe and “of”:
A friend of my mother’s→ A friend of my mother OR My mother’s friend
