What is a possessive and how to build it

Use possessives to show who owns something. Add 's to most nouns and plural nouns without an s. Use ' only for plural nouns ending in s.

When to use possessives

  • To show ownership (e.g. my dog’s tail).
  • To name people with family names (e.g. Smith’s house).
  • To describe time or distance (e.g. a day’s pay).

Examples of correct possessives

  • Tom’s bike is red.
  • My teacher’s car broke down.
  • We fixed the children’s swing.
  • The government’s new rule surprised everyone.
  • She fixed your parents’ laptop.
  • 5 minutes’ break is not enough.

Common mistakes and fixes

  • Wrong: Teachers houses. Correct: Teachers’ houses.
  • Wrong: The book of John. Correct: John’s book.
  • Wrong: All of her’s. Correct: Hers — use pronouns not possessives

Quick memory tip

Add 's like magic shoes: always at the end. Plural nouns already in s? Just add an apostrophe!
