Contractions

The forms like I’ve, don’t etc. are called contractions. There are two kinds:

Auxiliary verb + not

Noun / pronoun / etc + auxiliary verb

Contractions are formed with modal auxiliary verbs, and also with be and have when they are not auxiliary verbs.

The contracted form ‘s can be written after nouns, pronouns, questions words, here and now.

The short forms ‘ll, ‘d and ‘re are written after pronouns and unstressed there.

In other cases we usually write the full forms.

Contractions are not usually written with double subjects.

Note that in a contraction the apostrophe goes in the same place as the letters that we leave out.

Note that shan’t and won’t have only one apostrophe each although words are left out in more than one place.
