The Rules: How to Use the Apostrophe for Possession

The core function of the apostrophe for possession is to show that something belongs to someone or something. The rules vary slightly depending on whether the noun is singular or plural.

1. For Singular Nouns: Add ‘s to the end of the singular noun.
   • Example: the dog’s bone, Maria’s book, the car’s engine.
2. For Plural Nouns Ending in ‘s’: Add only an apostrophe ‘ after the existing ‘s’.
   • Example: the dogs’ leash (multiple dogs), the students’ projects, the companies’ policies.
3. For Plural Nouns Not Ending in ‘s’: Add ‘s to the end of the plural form.
   • Example: the children’s toys, the women’s club, the people’s choice.
4. For Singular Nouns Ending in ‘s’: There are two accepted styles. Adding ‘s is generally preferred for clarity of possession.
   • Example: James’s car (or James’ car – both are correct, but consistency is key).
5. For Joint Possession: When two or more people own something together, add the ‘s only to the final name.
   • Example: John and Jane’s house (they own the house together).
6. For Separate Possession: When two or more people own items separately, add ‘s to each name.
   • Example: John’s and Jane’s laptops (they each have their own laptop).

Important Tips for Students and Exam Candidates

• Its vs. It’s: This is the most common error. Its (without an apostrophe) is the possessive form, meaning “belonging to it.” It’s (with an apostrophe) is a contraction of “it is” or “it has.”
  • Correct: The dog wagged its tail.
  • Correct: It’s a beautiful day.
• Your vs. You’re: Your shows possession (your book). You’re is a contraction of “you are.”
• Their vs. They’re vs. There: Their shows possession (their house). They’re is a contraction of “they are.” There refers to a place.
• Avoid the “Greengrocer’s Apostrophe”: Never use an apostrophe for simple plural nouns (e.g., apple’s for sale is incorrect; it should be apples for sale).
• Pronouns are Exceptions: Possessive pronouns like his, hers, its, ours, yours, theirs do not use an apostrophe.
• Exam Strategy: In competitive exams, questions often test these common confusions (its/it’s, your/you’re). Read the sentence carefully to determine if you need a possessive (no apostrophe for pronouns) or a contraction (requires an apostrophe).

Frequently Asked Questions (FAQs) on Apostrophe for Possession

Q1: Where does the apostrophe go for a name ending in ‘s’, like James?
A: Both “James'” and “James’s” are considered correct. However, “James’s” is often preferred in modern style guides (e.g., Chicago Manual of Style) for clarity of pronunciation. The key is to be consistent throughout your document.

Q2: How do I show possession for a compound noun or phrase?
A: Add the ‘s only to the last word of the compound noun.

• Example: my mother-in-law’s recipe, the Attorney General’s duties, somebody else’s problem.

Q3: Do I use an apostrophe for possessive pronouns like ‘hers’ or ‘yours’?
A: No. Possessive pronouns like hers, yours, ours, its, and theirs are already possessive in their meaning and do not require an apostrophe. Using one (e.g., her’s, your’s) is always incorrect.
