Etymology: "Encrusting" is the present participle of "encrust", which means to cover a surface with a hard layer. The verb came into English from French "incruster", itself taken from Latin "incrustare", built from "in-" meaning "in" or "on" and "crustare", "to cover with a crust". The Latin root "crusta" meant a rind, shell or hard outer coating, and that concrete sense of a surface hardened over something softer is still what the word carries. English speakers often read the initial "en-" as a separate prefix added to "crust", and the modern form does look that way. The history runs the other way round: the Latin "in-" was taken into French as "in-" and only later shifted in spelling, so the English word preserves the Latin prefix in its original shape rather than an invented "en-" attached to a noun.

Synonyms: covering, coating
