We use apostrophes to indicate a possessive noun. Follow these rules to create possessive nouns with apostrophes.
- Add [‘s] to the singular form of the word (even if it ends in –s).
Ex. the owner’s insurance, the waitress’s coat
- Add [‘s] to the plural forms that do not end in –s.
Ex. the children’s game, the people’s opinion
- Add [‘] to the end of plural nouns that end in –s.
Ex. the three friends’ cars, the workers’ benefits
- Add [‘s] to the end of compound words.
Ex. my brother-in-law’s money
- Add [‘s] to the last noun to show joint possession of an object.
Ex. Tom and Monica’s house
Apostrophes are also used in contractions. We define a contraction as a word in which one or more letters have been omitted. The apostrophe shows this omission.
- don’t = do not
- I’m = I am
- he’ll = he will
- you’re = you are
- won’t = will not
- could’ve = could have
For each sentence, insert missing apostrophes or omit unnecessary apostrophes.
