1660, from Modern Latin pendulum (1643), noun use of neuter of Latin adjective pendulus “hanging down,” from pendere “to hang” (see pendant). The Modern Latin word is perhaps a Latinization of Italian pendolo.
A mass hung from a fixed support so that it is able to swing freely under the influence of gravity. Since the motion of pendulums is regular and periodic, they are often used to regulate the action of various devices, especially clocks.
