Principal Parts of Regular Verbs


A verb's tenses are made from four basic forms. These forms are called the verb's principal parts.


Present Present Participle Past Past Participle
stop (am, is, are) stopping stopped (has, have, had) stopped
ask (am, is, are) asking asked (has, have, had) asked


The present and the past forms can be used by themselves as verbs.

The present participle and the past participle are always used with a helping verb.
