Etymology

Origin of machine

First recorded in 1540–50; from French, from Latin māchina, from Doric Greek māchanā́ “pulley,” akin to mâchos “contrivance”; cf. mechanic

Explanation

At its simplest, a machine is an invention that does a job better and faster and more powerfully than a human being. Despite being man-made we’ve come to think of the word machine as the very opposite of human. The Machine Age we live in is considered impersonal and overwhelming, and anything machine-like is often considered soulless or even dangerous. (Witness the countless fantasies of robots taking over the world.) Human beings working together, like "the cogs of a machine," can become more powerful than a single person. That's why sports teams or political organizations are often described as "well-oiled machines."
