to make something look like marble or to cover it with marble.
From en- + marble (from Old French marbre, from Latin marmor). The prefix en- converts the noun into a verb meaning to give marble-like qualities or appearance to something.
Ancient Romans became obsessed with marble and invented techniques to fake it on cheaper materials—'enmarble' captures that same desire to make ordinary things look luxuriously expensive that still drives interior design today.
