What Is the Base Form of a Verb? (with Examples)

Base Form of a Verb (with Examples)

The base form (or root) of a verb is the form listed in the dictionary.

It is the version of the verb without any endings (endings such as -s, -ing, and ed). The base form is the same as the infinitive (e.g., to walk, to paint, to think) but without the to.

The base form is one of five verb forms in English.

Why Should I Care about the Base Form?

Understanding the verb forms (including the base form) is useful when learning English because it allows teachers and pupils to talk about the components that form the various tenses.

For example, with some verbs, the base form, past form, and past participle form are the same (e.g., let, I let, I had let). However, with others, they are all different (e.g., take, I took, I had taken).

Knowing the various verb forms is a great starting point for learning these complex rules and exceptions.
