What is the effect of enjambment in this excerpt from "porphyria's lover" by robert browning? that moment she was mine, mine, fair, perfectly pure and good: i found a thing to do, and all her hair in one long yellow string i wound three times her little throat around, and strangled her. no pain felt she; it creates a sorrowful mood. it conveys pain. it enhances the shocking effect. it introduces a pause.
