Clock

July 10th, 2008

A clock is an instrument for measuring, indicating and maintaining the time. The word clock is derived ultimately (via Dutch, Northern French, and Medieval Latin) from the Celtic words clagan and clocca meaning “bell”. For horologists and other specialists the term clock continues to mean exclusively a device with a striking mechanism for announcing intervals of time acoustically, by ringing a bell, a set of chimes, or a gong.[citation needed] A silent instrument lacking such a mechanism has traditionally been known as a timepiece. In general usage today, however, a “clock” refers to any device for measuring and displaying the time which, unlike a watch, is not worn on the person.
