History and Etymology for crust

Middle English crouste, cruste, borrowed from Anglo-French & Latin; Anglo-French cruste, crouste, going back to Latin crusta "hard coating or surface layer, shell of an arthropod or crustacean, mineral flake, stone slab used in paneling," perhaps, if going back to *krus-to- "something crushed or pounded into a hard layer," from a zero-grade nominal derivative of Indo-European *kreu̯s- "beat, crush, pound," whence also Old English hruse "earth, ground," Old High German roso, rosa "crust, layer of ice" (going back to Germanic *hrusōn-) — more at anacrusis

Note: The hypothetical base *krus-to- is suggested by Michiel de Vaan, Etymological Dictionary of Latin and the Other Italic Languages (Leiden: Brill, 2008), p. 147, though the older handbooks (Walde-Hoffman, Ernout-Meillet) tend to support a connection with Greek krýos "icy cold, frost" and other derivatives, going back to a presumed homonymous *krus- (see cryo-). As de Vaan points out, however, Latin crusta does not mean "ice." The original sense of the Germanic noun *hrusōn- is not certain. Greek krýstallos "ice, rock crystal" is almost certainly unrelated (see crystal entry 1).
