The first- and second-person singular, and the plural present-tense form of a verb. In English grammar, the base form of a verb is the simplest form, without a special ending (or suffix). It's the form that appears in dictionary entries.
The base form of a verb functions as the present-tense form for all persons and numbers except the third-person singular (which uses the -s form). The base form also functions as the infinitive (with or without to) and as the subjunctive mood for all persons including the third-person singular.
In addition, the base form is used for the imperative mood.

- Base Forms of Regular Verbs
"Main verbs are either regular (such as call, like, try) or irregular (such as buy, drink, set). 'Regular' means that we can state all the verb forms of an English verb once we know its base form. The base is the basic, uninflected form which is given as the entry form in dictionaries. . . . A regular English verb, such as call, has the following four forms:
- the base: call
- the -s form: calls
- the -ing form: calling
- the -ed form: called
The vast majority of English verbs are regular."
