Modals

Modals are helping verbs
Used with the base form of the verb, modals create verbal phrases.
Modals do not change form.
Modals never end in “s” even in 3rd person singular
Use “not” to make modal verbs negative.
Don’t use double modals.
Modals lack past tense forms, except could and would which serve as the past of can and will.
