Past tense of regular and irregular verbs
Topic: Past tense of irregular and regular verbs Regular verbs Forming the past simple tense of regular verbs is straightforward, and you use the same form for singular and plural: If the basic form of the verb ends in a consonant or a vowel other than e, add the letters -ed to the end (e.g. seem/seemed, laugh/laughed, look/looked).
Irregular verbs An irregular verb is one that does not form its simple past tense or its past participle by adding "-ed" or "-d" to the base form. Irregular verbs contrast with regular verbs, which form the simple past tense and past participle by adding "-ed" or "-d."
