How do you form the past tense irregular and regular verb?

Answer 1

The past tense of regular verbs is formed by suffixing "-ed" to the plural present indicative, unless that form ends in the letter "e", in which instance only "d" is suffixed to form the past tense; the word thus formed will also be the past participle. In some instances, the final consonant of the regular verb must be doubled before suffixing, particularly when the verb ends in a single consonant immediately preceded by a single vowel, so that referring to a dictionary is recommended. The past tense forms of irregular verbs must be learned individually, particularly because a few verbs, such as "hang", have two different past tense forms, depending on the meaning of the present tense.

Answer 2

To form the past tense of regular verbs, add "-ed" to the base form of the verb (e.g. "walk" becomes "walked"). Irregular verbs do not follow this rule, so you must memorize their past tense forms (e.g. "go" becomes "went").
