History and Etymology for ganoid

Adjective

after French Ganoïdes, order name (latinized as Ganoidei), from Greek gános "brightness, sheen, gladness, joy," (abstract noun derivative from gánymai, ganýnai "to brighten up, be glad," going back to Indo-European *gh2-n-u- derivative of *geh2u̯- "be glad") + -oïdes, plural of -oïde -oid entry 1
