Meaning of CLOCK in English

CLOCK

(n.) A machine for measuring time, indicating the hour and other divisions by means of hands moving on a dial plate. Its works are moved by a weight or a spring, and it is often so constructed as to tell the hour by the stroke of a hammer on a bell. It is not adapted, like the watch, to be carried on the person.
