Did you know?

We can only [conjecture](https://www.merriam-webster.com/dictionary/conjecture) the exact origin of conundrum. What is known is that the word has been in use since the 1600s, and that it had various spellings, such as conimbrum, quonundrum, conuncrum, and quadundrum, before the current spelling was finally established in the following century. One theory of origin suggests that the word was coined as a parody of Latin by students at Oxford University, where it appears to have enjoyed particular popularity in its "word play" or "pun" sense. While the prevalent sense in this century is that of the seemingly unanswerable question or problem, frequently applied to heady dilemmas involving ethics, sociology, or economics, the word is sometimes so loosely applied to anything [enigmatic](https://www.merriam-webster.com/dictionary/enigmatic) as to be synonymous with puzzle or mystery.
