Late Middle English; earliest use found in John Trevisa (c1342–?1402), translator. From classical Latin supercilium eyebrow, haughtiness, overhanging edge, brow, small hillock, projection in a coastline, (in architecture) overhang, (in a door frame) lintel, in post-classical Latin also lip or margin of a bony cavity, probably from super- + cilium, although cilium is first attested later and may be derived from supercilium.
