A clatter is a clacking or rattling sound, like the clatter of horse hooves on pavement or the clatter of toys being thrown down a wooden staircase by an angry child.

Clatter is also a verb, meaning "to make a continuous rattling or clanking sound." You might clatter down the school hallway in your clogs, or watch your dogs clatter across a frozen pond, their toenails clicking on the ice. Clatter comes from the Old English onomatopoeic clatrung, "a clattering," or simply "noise."
