crust

crust: [14] Latin crusta meant ‘hard outer covering, shell’ (it is related to a number of words, including ultimately crystal, denoting a hard surface caused by freezing). Old French acquired it as crouste (the modern French form cro?te formed the basis of cro?ton, borrowed into English in the early 19th century), and passed it on to Middle English as cruste. Crusta formed the basis of the modern Latin adjective crustāceus ‘having a shell’, applied in the early 19th century to the crustacea or crustaceans. And a custard was originally a kind of pie enclosed in a crust.
=> cro?ton, crystal, custard
