Its or it’s? Your’s or yours? People’s or peoples’? Using apostrophes and apostrophe “s” can be very confusing. Here are a few rules to follow:
“Hers” never has an apostrophe— just as “his” doesn’t.
“It’s” is an abbreviation for “it is”: It’s a fine night for a walk by the ocean. I’d like to go out, but it’s pouring rain.
“Its” (without an apostrophe) shows possession: The train was slow, and its caboose was rusty. (The caboose belongs to the train.) The cat arched its back. (The back belongs to the cat.)
Singular and plural possessives: If a noun is singular (only one), then add ‘s, even if the word ends in s: The woman’s mouth; James’s mouth
If a plural noun ends in an s, simply add an apostrophe after it: Four of my cousins’ apartments; three bankers’ cars
If more than one person owns something, add ‘s to the second name: Jack and Julia’s love affair was exciting to read about!
