Today I'm going to talk about apostrophes. This is probably the most misused punctuation I see, and it is my personal pet peeve.
The primary use for apostrophes is to show ownership.
the owner's car
the children's toys
The mistake I see most often is using an apostrophe to make a word plural:
the guy's
When a word ends with "s", there are two ways to use an apostrophe and both are correct:
Add "'s":
the boss's desk
Add an apostrophe:
the boss' desk
To make a plural word show ownership, simply add an apostrophe.
the guys' night out
Wrong: the guy's night out (this means their is only one guy)
The other use for an apostrophe is in a contraction. The apostrophe goes where the letter that is left out would go.
Doesn't NOT does'nt
