Possessive nouns are used to indicate ownership.
A noun names a person, place, thing, idea, quality or action. A possessive noun shows ownership by adding an apostrophe, an “s” or both. To make a single noun possessive, simply add an apostrophe and an “s.”
- John’s book
- Ben’s car
- Grandma’s mirror
When a noun is plural and ends in s, just add an apostrophe (‘).
- The kids’ toys
- My parents’ house
- The teachers’ lounge
If two people own one thing, add the apostrophe and s to the second person only.
- John and Mary’s new house
- David and Beth’s wedding
- Tom and Julie’s car
If two people own separate things, add the apostrophe and s for each person.
- Susan’s and Beth’s books
- Jean’s and Matt’s pants
- Luca’s and Leonardo’s offices
