Base form

From Teflpedia

The base form (/ˈbeɪs ˈfɔ:(r)m/) is a verb form form that has various uses in English, and is also used as the basis for other forms.

Form[edit | edit source]

For lexical verbs, the base form is used for (1) the bare infinitive and (2) the finite conjugations for all present tense lexical verbs except the third person singular, present tense, indicative mood.

It is also the basis for the following derived forms:

The main exception is the verb be, which is highly irregular. It has the base form "be", from which can be formed a to infinitive "to be", and an -ing form "being". However, its conjugation is all irregular.

Full modal verbs also have a base forms, i.e. can, may, must, shall, will. They lack -ing forms and infinitives.
