Irregular verbs don't follow a set pattern to form their past tense and past participle. Like a loose cannon, an irregular verb doesn't play by the rules.
You know what that means: the best way to master irregular verbs is simply to acquaint yourself with as many of them as you can. Translation: memorize.
