encrustation

The word 'encrustation' is built upon the Latin noun crusta, meaning a hard, baked surface like a shell or a rind. The prefix en- (from Latin in-), adopted into English via French, was added to form the verb 'encrust,' meaning "to cover with or form into a hard crust." Finally, the Latinate suffix -ation was appended to create the noun, signifying either the action of forming a crust or the resultant crusted layer itself. This etymological path clearly illustrates the transformation from the simple concept of a hard shell to the more specific process or product of one surface becoming adhered to another.
