Definition
A brush is a tool with bristles, wires, or other filaments, used for cleaning, grooming, or applying substances. Imagine using a paint brush to create a masterpiece; each stroke contributes to the whole picture. Figuratively, a 'brush' can be a light or glancing contact, like a quick touch. It can also be a brief encounter or experience. Think of it as a quick pass – leaving a subtle mark or impression.
