The English language uses both regular and irregular verbs. When forming the past tense or the present/past perfect tense of these verbs, we use different methods.
To form the past tense of a regular verb ending with a vowel (a, e, i, o, u), add a d to the word. To form the present/past perfect tense, add a d plus a helping verb (have, had, or has). For example, the verb share ends with the vowel e. share = present tense shared (share + d) = past tense had shared (had + share + d) = past perfect tense (have is the helping verb)
If the regular verb ends with a consonant, add ed for the past tense. Add ed plus a helping verb for the present/past perfect tense.
For example, the verb pour ends with the consonant r. pour = present tense poured (pour + ed) = past tense have poured (have + pour + ed) = present perfect tense
(If you need help understanding tense, please ask a CWC instructor for a handout on definition of tense.)
Unlike regular verbs, irregular verbs do not follow a pattern. You must memorize them.
For example, the irregular verb see has three principal parts: see, saw, seen.
I see the stars= present tense
I saw the stars= past tense
I have seen the stars= present perfect tense
Below is a list of irregular verbs and a few tricky regular verbs that students often misuse. Cover the columns marked past and present/past perfect, leaving the present column visible. Now read the verbs in the present column and see if you know their past and present/past perfect forms. If not, keep memorizing!
