palinode (n.)

"a word or line that reads the same backward and forward," 1620s, from Greek palindromos "a recurrence," literally "a running back." Second element is dromos "a running" (see dromedary); first is palin "again, back," from PIE *kwle-i-, suffixed form of root *kwel- (1) "revolve, move round." PIE *kw- becomes Greek p- before some vowels. Related: Palindromic; palindromist.

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.
