How to Conjugate Verbs in English

To conjugate a verb in English means to correlate the different forms of the verb with the various points of view of the subject. The points of view are first, second, and third person singular and first, second, and third person plural. All tenses can be conjugated, but most grammar textbooks focus on conjugating regular verbs in the present tense and the three irregular verbs " to be," "to do" and "to have" in the present and past tenses, because these are where most students make errors.

Conjugation of Regular Verbs

To conjugate a verb, make a list of the six points of view, which include three singular points of view and three plural points of view. First person refers to the person or people speaking (I and we). Second person refers to the person or people being spoken to (you). Third person refers to the person or people being spoken about (he, she, it or they).

Present tense conjugation of a regular verb (example: to walk): Singular:
I walk you walk he, she, it walks

Plural: we walk you walk they walk

*The third-person singular verb always ends in "s."

Past tense conjugation of a regular verb (example: to walk): Singular: I walked you walked he, she, it walked

Plural: we walked you walked they walked

*The past tense of regular verbs ends in "ed."

Present perfect tense conjugation of a regular verb (example: to walk): Singular: I have walked you have walked he, she, it has walked

Plural: we have walked you have walked they have walked

• For regular verbs, the past tense and the past participle of the verb are the same.

Conjugation of Irregular Verbs

Irregular verbs are conjugated the same way as regular verbs in the present tense. For the past tense and the perfect tenses, irregular verbs must be memorized because they do not follow the rules that regular verbs do.
