From Latin locusta.


locusta f (plural locuste)

  1. locust


Alternative formsEdit


The origin is uncertain. According to De Vaan, the only word similar in form and meaning is lacerta (lizard; mackerel) and “they could be cognate words in the language from which Latin borrowed these forms”. Pokorny connects locusta and lacerta with Ancient Greek λάξ (láx) λάγδην (lágdēn, with the foot, adverb), λάκτις (láktis, pestle), λικερτίζειν (likertízein, to jump, to dance) and Old Norse leggr (lower leg, bone), Lombardic [Term?] (lagi, thigh), deriving all from Proto-Indo-European *lek- (joint, member; to bend, to wind), explaining locusta as “equipped with joints”. This is considered unconvincing by De Vaan.
