Etymology: "Clacks" is the plural of "clack", and the noun and verb both trace back to a Germanic root meaning to clap or chirp. The verb entered Middle English as "clacken" and related forms, descending from Old English "clacian", which meant to slap, clap or clack. The sound-imitative character of the root shows in its neighbours: Dutch "klakken" means to clack or crack, Norwegian "klakke" means to strike or knock, and Icelandic "klaka" once meant to twitter or chatter. Scots "clake" and "claik" meant both to utter cries and to bedaub something with a sticky substance, a pairing that suggests how closely the sense of noisy striking and messy smearing once sat together.

Synonyms: clicks, clatters, taps
