Definition
"Clack" refers to a sharp, snapping sound, like two hard objects hitting each other. It's often a short, percussive noise. Think of the sound of high heels on a hard floor, or the sound a pair of scissors makes when they close. It can also describe rapid, continuous talk, often in a gossipy or chattering way. So, it's either a sound or a kind of noisy speech. π£οΈ
