Chapter The modals

The modals are:
will/would, can/could, shall/should, may/might and must.
These verbs are used to indicate the modality of a sentence. They allow us to express an opinion, to state a judgment, to impose an obligation.

The modals lack an infinitive form, meaning that they are never preceded by « to ».
The modals are never followed by « to ».
They do not take an “s” in the third person singular.
Example : He will need help.
The modals cannot end in “ing”.
They do not require the auxiliary «do» in order to form the negative.
Examples : He must not, he cannot, …
« Must » cannot have a past tense form.

We have the following contracted forms:
must not → mustn't cannot → can't
will not → He won't
will ou shall → 'll
might not → mightn't
shall not → shan't
would → 'd
would not → wouldn't
should not → shouldn't
could not → couldn't
