Etymology

Origin of flummox

First recorded in 1830–40; origin uncertain

Explanation

Does the word flummox bewilder, confound, dumbfound and generally mystify you? Well, fear no more, because flummox means all of these things! Things that flummox you are probably not that serious, and often pretty amusing and informal: a TV remote or a crossword puzzle, for example, rather than something major like why your boyfriend or girlfriend broke up with you. (Now that's unfathomable.) Get this: linguists are actually mystified as to where the word flummox comes from — they're flummoxed, in other words. It may come from an old English word, flummock, meaning "to make untidy or confuse," but no one is really sure. Now, what could be more suitable?
