About the Word:
It should be stated at the outset that the parentage of glitch is not assured, something we should not hold against so useful a word. Merriam-Webster states (as do many other dictionaries) that the word is 'perhaps from Yiddish glitsh,' a word that means 'slippery place.' The first known print use of the word is from 1940, when it was reported as being used in the slang of radio announcers, referring to an egregious mispronunciation.
