Forms

langouste f (plural langoustes)[1] Old French languste (12th century) and langoute (13th century).[2][3]

Etymology

It is borrowed from Old Occitan langosta (“locust; spiny lobster”),[2][4][3][5] from Vulgar Latin *lacusta, with a secondary nasal, a form altered, probably by vowel dissimilation, from Latin locusta (“locust; spiny lobster”).[2][4][3] Bloch and Wartburg prefer dissimilation to a crossing with Latin lacertus (“lizard”).[3] The origin of the Latin word is uncertain.[4][1]

The inherited Old French form was laöste (“locust”), and a learned locuste was taken from Latin about 1120.[2][4] Cognate with Romanian lăcustă, Catalan llagosta, Spanish langosta and Portuguese lagosta.[6][7]

Earliest recorded meaning

It is first found as languste in the Lapidaire de Marbode in the first half of the 12th century, meaning the locust or grasshopper.[2][4] Brunetto Latini says of John the Baptist: Sa viande fu miel et langoustes (“his food was honey and locusts”).[7]

Semantic evolution

The sense “locust” lasted until the 17th century and is still used by Corneille.[4][3][8] The crustacean was first named in the phrase langouste de mer in the Ménagier de Paris (1393): Langoustes sont grans escrevices (“langoustes are large crayfish”).[2][4][7] Littré compares the Norman coasts, where shrimps are called sauterelles.[7] Both senses are still used in southern French dialects.[3]

In slang, langouste and langoustine have meant a prostitute or a mistress since about 1930, as sauterelle has.[4]
