A reader asked for a post about using apostrophes to make possessives. Here are the basic rules:
* Add ‘s to all singular common nouns and to plural common nouns that don’t end in s: the boy’s toys, a day’s time, the boss’s husband, the children’s clothes.
* Add ‘ (apostrophe only) to plural common nouns that end in s: the boys’ toys, the churches’ disagreement
The Associated Press Stylebook notes this exception: Add ‘s to singular nouns that end in s EXCEPT when the next word begins with s: the boss’ specialty, the witness’ story. Not all style guides agree with that.
For proper nouns, here are the basic rules:
* Add ‘s to proper nouns that don’t end in s: Pam’s blog, Mr. Smith’s class, Carolina’s team, Martinez’s car, Foxx’s campaign, the Children’s Defense Fund * Add ‘ (apostrophe only) to proper nouns that end in s: the Kennedys’ compound, the Smiths’ mailbox, Reynolds’ seats, Descartes’ theories, Chris’ Web site. * But many style guides (and standard British practice) say to add ‘s to singular proper names that end in s: Chris’s Web site, Charles’s books, Reynolds’s seats.
You can apply these rules almost every time you need to make a noun possessive.
