I know you can put pi before an adjective to make the -er in English, like pi bèl means prettier. Or pi can mean more, like pi enpòtan means more important. First question: Can you use pi with ANY adjective? I don't think I've ever heard it with many different adjectives like pi vye or pi nèf. Also I know you can use pi with verbs, like, "Sa ou pi renmen?" meaning "What do you like most?" Second question: Can you use it with ANY verb? Please give examples if possible. Thanks!
