Forms

lutra f (genitive lutrae); first declension[1] Varro has the spelling lytra.[2][3]

Etymology

It is inherited from Proto-Italic *udrā-, inherited from Proto-Indo-European *ud-ro-, an adjective meaning “of the water” that came to name a water animal, the otter.[4] The change of PIE /dr/ to Latin /tr/ is regular, but the initial ⟨l⟩ is a later addition: de Vaan suggests it may come from lavō (“to wash”), or, since the otter is a carnivore, from lupus (“wolf”), and also considers the influence of lūdō (“to play”), as otters are playful.[4] Wiktionary likewise explains the ⟨l⟩ by analogy.[1] The feminine gender, which Latin shares with Balto-Slavic, probably generalises the feminine of the adjective.[4] The OLD calls the origin doubtful.[5]

Cognate with Sanskrit उद्र (udrá-), Avestan udra-, Lithuanian ū́dra and Old Prussian wudro, all meaning “otter”, with Ancient Greek ὕδρος (húdros, “water snake”), and with Old High German ottar and Old Norse otr.[4]

Varro derived the word from luō (“to loosen”), because the otter was said to cut through the roots of trees on the bank.[6]

Earliest recorded meaning

It is first found in Varro,[4] in the form lytra, for the otter.[2][3]

Semantic evolution

Pliny the Elder describes the otter beside the beaver, noting that both live in water.[6][2] In British Medieval Latin it remained the word for the otter, with forms such as lutrea and lutrius;[7] Bede mentions sea creatures that people call lutreae.[7] Through Vulgar Latin forms reshaped by analogy it gave Italian lontra and French loutre.[1]
