means A tool with bristles fixed to a handle, used for applying paint or similar liquid to a surface.

from A straightforward compound: 'paint' (from Old French 'peint,' past participle of 'peindre,' to paint, from Latin 'pingere,' to paint or depict) joined with 'brush' (from Old French 'broisse/brosse,' a word for brushwood or bristly material, itself of uncertain deeper root). The two words fused in English once brushes became the standard tool for applying paint — a plain, functional naming with no hidden story, just utility wearing its purpose on its sleeve.
