showerhead

The word "showerhead" is a transparent Modern English compound, formed by combining two native Old English roots. "Shower" evolved from Old English scūr, referring to a brief fall of rain, a concept later applied to a bathing device that replicates this experience. "Head" derives from Old English hēafod, which, beyond its anatomical sense, developed a broad metaphorical use for the source, top, or leading part of an inanimate object (e.g., riverhead, spearhead). The compound's logic is perfectly literal: it names the "head" or outlet fixture of the "shower" apparatus, directly describing its form and function.

Structure: shower + head - shower (Old English scūr, meaning "a short fall of rain, hail, or sleet"): The core element denoting the bathing apparatus that simulates a rain-like spray of water. - head (Old English hēafod, meaning "the top or front part of the body; the uppermost part"): A metaphorical extension meaning the top, front, or terminal part of an object. Here, it signifies the terminal fixture from which the water emerges.
