Etymology

The word "paintbrush" is a straightforward compound of "paint" (from Old French peintier, meaning "to decorate with color") and "brush" (from Old French broisse, meaning "a tool with bristles"). The combination reflects its literal function—a brush designed specifically for applying paint. Over time, it has also gained metaphorical use in artistic contexts.
