Word History

Etymology

Middle English cantaride (usually in plural) "the blister beetle Lytta vesicatoria (earlier Cantharis vesictoria), preparation made from the beetles," borrowed from Latin cantharid-, cantharis (plural cantharidēs) "the beetle Lytta vesicatoria," borrowed from Greek kantharís, from kántharos "the dung beetle Gymnopleurus mopsus" (of obscure origin) + -id-, -is, diminutive suffix

Note: The Greek word kántharos denotes various things (beetle, cup, a kind of boat, a species of fish) the interrelations of which are far from clear; possibly several words of distinct origin have merged.
