Word Origin for sturgeon
c.1300, from Anglo-French sturgeon, Old French esturjon, from a Germanic source (cf. Old High German sturio "sturgeon," Old English styria), from Proto-Germanic *sturjon-; cognate with Lithuanian ersketras, Russian osetr "sturgeon." Of obscure origin, perhaps from a lost pre-Indo-Eeuropean tongue of northern Europe, or from the root of stir. Medieval Latin sturio, Italian storione, Spanish esturion are Germanic loan-words.
