Regular verbs form their past and past participle forms by adding -d or -ed to the verb's present tense. Thus, "use" becomes "used", and "call" becomes "called".
Irregular verbs form their past and past participle forms differently. The present tense "break" becomes "broke" in its past-tense form and "broken" in its past participle form. The present tense verb "buy" becomes "bought" in its past and past participle forms.
