Contractions

You will want to learn how to use contractions as soon as possible. Contractions are used constantly in informal English. Examples of contracted subject/verb forms are:

TO BE

I am–>I'm
he is–>he's
we are–>we're
you are–>you're
they are–>they're


TO HAVE


I have–>I've
we have–>we've
you have–>you've
they have–>they've


Contractions are frequently used with compound forms of verbs, especially the progressive or continuous form of the present tense (I'm going. / We're leaving.) and the present perfect forms (I've received the letter. / They've already left.)
