词源

Etymology tree Proto-Indo-European *lek-der.? Latin locusta Anglo-Norman locustebor. Middle English locuste English locust Inherited from Middle English locuste, locust, from Anglo-Norman locuste, Middle French locuste, and their source, Latin locustam (“locust, crustacean, lobster”, accusative of locusta). Doublet of langouste. Noun sense 3 (“kind of tree”), originally referring to the carob (compare locust bean), is based on the resemblance of the trees' beanlike seed pods to the insect and is likely a semantic loan from Ancient Greek ἀκρίς (akrís). Noun sense 5 (“mainlander”) is a semantic loan from Cantonese 蝗蟲 /蝗虫 (wong4 cung4), also meaning "locust".
