the.com/area rug

means A rug sized to cover only part of a floor, rather than wall-to-wall carpeting fixed in place.

from Straightforward compound English: 'area' (from Latin area, an open space or plot of ground) plus 'rug' (likely from a Scandinavian source, related to Norwegian rugga, 'coarse coverlet' or rough cloth). Wall-to-wall carpet came first as the dominant fashion, nailed and fitted to a whole room; 'area rug' arose as the practical label for the smaller, movable alternative — naming it by what it covers, an 'area,' rather than the whole floor.
