Did you know?

Kinetic comes from the Greek word kinētikos, meaning “of motion,” which in turn traces to the verb kinein, meaning “to move.” Compared to some other English words that have their roots in Greek, kinetic is a relatively young English word; the earliest evidence we have of its use is from the 19th century. Although it deals with the motion of images rather than material bodies, the word cinema is also related to kinein. The verb kinein is the source of the Greek kinēma, meaning “movement,” to which the French referred in the coining of their cinématographe. Cinématographe is the word that gave rise to the English word cinematograph, of which cinema is simply a shortened form.
