There are two types of verbs in English: regular verbs that conjugate in the simple past and past participle by adding "-ed", and irregular verbs that change form or stay the same between the present, simple past, and past participle. Regular verbs are formed by adding "-ed", while irregular verbs have unique forms for the simple past and past participle, such as "write-wrote-written" and "set-set-set".
