capa

cloak, cape (a sleeveless garment hanging from the neck); coat, sheet (a covering of material, such as paint); layer (a single thickness of some material covering a surface); guise; pretext

Inherited from Old Spanish capa, from Late Latin cappa. Cognate with English cape and cope (“priestly vestment”). Compare English coping (“top layer of a brick wall”) for an English comparable semantic sense of a "layer".
