prosody n.

word-forming element in words of Greek origin meaning "to, toward, before," from Greek pros (prep., adv.), also proti, "from, forth, from (one point) toward (another); furthermore; in the face of," from PIE *proti- (source also of Sanskrit prati "to, against").

1580s, from French ode (c. 1500), from Late Latin ode "lyric song," from Greek ōidē, an Attic contraction of aoidē "song, ode;" related to aeidein (Attic aidein) "to sing;" aoidos (Attic oidos) "a singer, singing;" aude "voice, tone, sound," probably from a PIE *e-weid-, perhaps from root *wed- "to speak." In classical use, "a poem intended to be sung;" in modern use usually a rhymed lyric, often an address, usually dignified, rarely extending to 150 lines. Related: Odic.
