“ Some stress only the F ending: жить "to live," живу, живёт, p жил, жила, жило, жили. Mostly such verbs draw the stress back to a preverb in the other p forms: занять "to occupy," займу, займёт, p занял, заняла, заняло, заняли, and they similarly stress the ppp forms: занятый "occupied," sh занят, занята, занято, заняты. ”
