- Apostrophes are used to show possession. Justin's ball, California's capitol, and the company's president, for example.
- Apostrophes are used to form contractions. Wouldn't (would not), He's (he is or he has), doesn't (does not), for example.
- Sometimes apostrophes are used to create plurals. Mind your p's and q's, for example. This is done so the reader is not confused.
Apostrophes have very few rules, yet they remain one of the most abused forms of punctuation.
