Principal Parts of Irregular Verbs
Usually you add -ed to a verb to show past tense. Irregular verbs do not follow this rule. Instead of having -ed forms to show past tense, irregular verbs usually change to other words.
Present Present Participle Past Past Participle
see (am, is, are) seeing saw (has, have, had) seen
There are many, many irregular verbs in the English language. For a more extensive list, please look online or refer to the list in Mrs. Rielage's classroom.
