I sometimes play Boggle at work. I usually lose to the resident Boggle players who are more experienced (at least lately) and have the 4-and-5-letter-words in L1 cache.
But sometimes I get to pull out a good word. Often a Britishism which sometimes passes muster with Merriam-Webster, our official arbiter. The other day I spotted monad which scored, and prompted quizzical looks from my competitors. When they said, “What’s a monad?” I of course said matter-of-factly, “A monad is a monoid in the category of endofunctors.”
