Noun + noun

Simplified etymology

Crust comes through Old French crouste from Latin crusta, meaning “rind,” “shell,” or “crust.” The same Old French word also gave rise to custard through the name of a pie with a crust.

Etymology

From Middle English cruste, from Anglo-Norman and Old French cruste, from Latin crusta (“hard outer covering”), from Proto-Indo-European *krustós (“hardened”), from *krews- (“to form a crust, begin to freeze”), related to Old Norse hroðr (“scurf”), Old English hruse (“earth”), Old High German hrosa (“crust, ice”), Latvian kruvesis (“frozen mud”), Ancient Greek κρύος (krúos, “frost, icy cold”), κρύσταλλος (krústallos, “crystal, ice”), Avestan 𐬑𐬭𐬎𐬰𐬛𐬭𐬀- (xruzdra-, “hard”), Sanskrit क्रूड् (krūḍ, “thicken, make hard”). Doublet of crusta.
