Contractions are words formed by joining two words and dropping letters. An apostrophe marks the dropped letters:
- we are
- there is
Use contractions to establish a personal, informal tone.
Contractions are not appropriate for very formal or ceremonial documents such as contracts or legal notices. However, contractions lead to a conversational, friendly tone in most other business correspondence. Contractions are common in electronic mail (email) messages because they cut the amount of screen space required.
- We’re excited that you’ll be joining our sales force!
- It’s been a long time since you’ve come to see us.

Don’t confuse contractions with possessive pronouns.
Writers often confuse contractions, which require apostrophes, with possessive pronouns, which need no apostrophes:
- It’s (it is) a regulatory issue.
- The company lost its lease.
- There’s (there is) no time to waste.
- The contract is theirs if they want it.
Watch out for these pronouns commonly mistaken for contractions:
- hers, not her’s
- yours, not your’s
- ours, not our’s
- theirs, not their’s
- it’s (it is)
- its (belonging to it)
- you’re (you are)
- your (belonging to you)
- they’re (they are)
- their (belonging to them)
