Dear M Anonymous, The past tense of “is” is “was” (singular) and “were” (plural); these are forms of the verb “to be.” The word “is” is the third-person singular present tense of “to be”; the other forms are “am” (first-person singular present tense) and “are” (plural present tense).
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.
