When to use shrank or shrunk
Past participle: ‘You’ve shrunk more than just your sweater from putting it in the dryer.’
The difference is in the past simple tense being a tense (slice of time) in which an action or event occurred and was completed. The past participle is a form of verb that does not, on its own, convey tense, and so uses a helping or auxiliary verb, such as had/have/has. Beyond that, the past participle forms the passive voice, and one of the perfect tenses. The perfect tense is a verb form that shows an action or state of being as complicated, but focuses more on the outcome or ‘resulting state rather than the occurrence itself.’
