anodyne

From Middle English anodine, from Medieval Latin anōdynos (“stilling or relieving pain”), from Ancient Greek ἀνώδυνος (anṓdunos, “free from pain”), from ἀν- (an-, “without”) + ὀδύνη (odúnē, “pain”). Adjective sense “noncontentious” probably through French anodin (“harmless, trivial”), of same origin.
