Hemistich

A hemistich (/ˈhɛmɪstɪk/; via Latin from Greek ἡμιστίχιον, from ἡμι- "half" and στίχος "verse") is a half-line of verse, followed and preceded by a caesura, that makes up a single overall prosodic or verse unit. In Classical poetry, the hemistich is generally confined to drama. In Greek tragedy, characters exchanging clipped dialogue to suggest rapidity and drama would speak in hemistichs (in hemistichomythia). The Roman poet Virgil employed hemistichs in the Aeneid to indicate great duress in his characters, where they were incapable of forming complete lines due to emotional or physical pain.
