means The structural border, usually of wood, metal, or plastic, that surrounds and holds a mirror in place.

from A plain compound of two old words doing exactly what they say. "Mirror" comes through Old French *mirour* from Latin *mirare*, "to look at, to wonder at" — the same root that gives us "miracle" and "admire," reminding us that catching your own reflection was once genuinely astonishing. "Frame" descends from Old English *framian*, "to be helpful, to make progress," tied to the idea of fitting pieces together into a useful structure. So a mirror frame is, etymologically, the wonder-glass held together by the thing that helps.
