köken: 16th century, from Middle Low German *hummer, itself from Old Norse humarr, perhaps through early Norwegian (as many lobsters were caught off the coast of Norway). From the same North Germanic source Modern Low German Hummer, Plautdietsch Humma, Dutch hommer.
köken: Cross of lobagante (which is from Vulgar Latin *lucopante, from Ancient Greek λυκοπάνθηρος (lukopánthēros, “snow leopard”) because of the fierce appearance of its large claws) with bogar (from Latin vocāre (“to call”)) and avante (from Latin ab + ante).
köken: From earlier aligusta, most likely from Latin locusta (probably through a Vulgar Latin form lacusta), with partial concretion or agglutination and false deglutination of the preceding article. Compare the borrowed doublet locusta.
köken: Later 19th century, at first in the form hummer. Ultimately from Old Norse humarr (“lobster”). The immediate source may be either German Hummer (16th c.) or directly from Dano-Norwegian hummer as many lobsters were caught off the coast of Norway.
Inherited from Old French langouste, languste, borrowed from Old Occitan langosta, from Vulgar Latin lacusta, from Latin locusta, of uncertain origin. Cf. also the Old French laöste, laüste, laouste, which was inherited from the Latin, as well as locuste, which was a learned borrowing.
