There's a glitch in the etymology of glitch - the origins of the word are not known for sure, though it may derive from the Yiddish glitsh, meaning "slippery place." The first documented use of glitch in print in English is found in astronaut John Glenn's 1962 book Into Orbit. In it he wrote, "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, you don't have to be an astronaut to be familiar with the word glitch, which can be used of any minor malfunction or snag.
: an unexpected and usually minor problem; especially : a minor problem with a machine or device (such as a computer)
