Etymology

The word "pillowcase" is a straightforward compound of "pillow" (from Old English pyle, meaning "cushion for the head") and "case" (from Latin capsa, meaning "box" or "covering"). The term emerged in the 17th century as a functional descriptor for the fabric cover enclosing a pillow. The logic is literal: a "case" that holds a "pillow."
