#14 - Regular and Irregular Verbs - English Grammar

"Regular verbs" are verbs that change very little from their base form when turned into past tense or past participle form.

Past tense verbs and past participles indicate that an action has been completed. While verbs in past tense can stand on their own, verbs in past participle form cannot stand alone as a verb.

For "regular verbs", we only have to add "-d" or "-ed" to the end of the verb to turn it into past tense or past participle form. For "irregular verbs", there is no set pattern to turn it into past tense or past participle form. An "irregular verb" can look like an entirely different word.

Regular verbs add "-d" or "-ed" to the end of the verb to turn it into past tense or past participle form
