Base form (of a verb)

The base form is the simplest form of a verb, which is a part of speech that describes an action, state, or occurrence. The base form can be added to in a number of ways depending on the tense or subject of the sentence. For example the base form of the verb ‘eat’ is in that form for first and second person, ‘I eat’, ‘you eat’, but changes when we use it for third person, i.e. ‘he eats’, ‘she eats’, etc.
