There's a glitch in the etymology of glitch—it may come from the Yiddish glitsh, meaning "slippery place," but that's not certain. Print use of glitch referring to a brief unexpected surge of electrical current dates to the mid-20th century. Astronaut John Glenn, in his 1962 book Into Orbit, felt the need to explain the term to his readers: "Literally, a glitch is a spike or change in voltage in an electrical circuit which takes place when the circuit suddenly has a new load put on it." Today, the word can be used of any minor malfunction or snag. If you’re a gamer you might even take advantage of a glitch that causes something unexpected, and sometimes beneficial, to happen in the game.
