Apostrophes to show possession

• When something is owned, you put an apostrophe after the last letter of the owner:

the boy’s cap

the boys’ caps

the children’s school

the ladies’ tea parties

• If two or more people share ownership, only the last owner needs an apostrophe:

This is Bruce and Pat’s boat.

• Be careful not to use an apostrophe with possessive pronouns!

his: Curry is his favourite dish.

its: My shoe has lost its heel.

theirs: They believe the land is theirs.
