Pronunciation

Forms

croûte f (plural croûtes)[1] Old French croste, cruste and crouste; the spelling croûte dates from the 17th century.[2][1][3]

Etymology

It is inherited from Middle French crouste, inherited from Old French croste, inherited from Latin crusta (“hard outer covering, crust (of bread, of a wound), inlaid plaque”).[2][4][1][5] The circumflex marks the loss of the ⟨s⟩.[1][3] The Latin word has been compared with Ancient Greek κρύος (krúos, “icy cold”), Old Norse hrjósa (“to shiver”) and Latvian kreve (“crust (of a glacier)”);[4] Wiktionary traces it to Proto-Indo-European *krustós (“hardened”), from *krews- (“to form a crust, begin to freeze”).[1]

Cognate with Old Occitan crosta, Italian crosta, Spanish costra, Portuguese crosta and Romanian crustă.[6][7][8]

Earliest recorded meaning

The first record, in the 11th-century glosses of Rashi, is croste of blood, a scab.[2][4] The sense of the pastry around a pâté follows about 1165 (Gautier d'Arras), and the crust of bread at the end of the 12th century.[2][4]

Semantic evolution

From a crust of blood the word became a medical term (1314, Henri de Mondeville), then named any hardened surface layer on something (1690), notably the earth's crust, croûte terrestre (1855).[2][4] Its figurative use for a superficial layer, as a croûte of learning (about 1230), gave way to vernis as the word grew pejorative.[4][2]

Other familiar figurative senses lasted: a bad painting (1757, from 1730 “a fake picture”), from a coat of paint daubed on the canvas, and a narrow-minded, routine-bound person, vieille croûte (1844), like a useless old crust.[4][2] In cooking, by contrast, it is not pejorative: casser la croûte “to have a bite to eat” is recorded from 1878 and gagner sa croûte “to earn one's living” from 1900, while the pastry sense gave pâté en croûte.[4][7][2]
