Contractions are a combination of two words. Often they are a pronoun and a verb. But not all verbs can be combined with a pronoun to form a contraction. Use only these verbs: have, has, is, are, am, would, and will. Look how these verbs form contractions with the pronouns:
| Pronoun | have/has | is/are/am | would/will |
| I | I’ve | I’m | I’d/I’ll |
| you | you’ve | you’re | you’d/you’ll |
| he | he’s | he’s | he’d/he’ll |
| she | she’s | she’s | she’d/she’ll |
| it | it’s | it’s | N/A |
| we | we’ve | we’re | we’d/we’ll |
| they | they’ve | they’re | they’d/they’ll |
| who | who’s | who’s | who’d/who’ll |
Certain verbs form contractions with the negative word not:
