Recently, I've noticed that the NY-Times Wordle game accepts the word "muist" as a five-letter word attempt. But what does it mean and where does it come from?
I've searched online and I stumbled upon a few scrabble-oriented resources that strongly indicate the word is a valid scrabble word (I assume the word is accepted by Wordle because the game imported some word list used for scrabble).
The meaning and origin of the word still remain unclear. scrabble-solver.com defines it as "to powder" and following that lead I came upon an entry in a Scots dictionary that seems to define it similarly. So one hypothesis is that it's a Scots word.
However, the Collins Scrabble Dictionary website has an "Official Word Checker" tool which, for this word only says "See must", suggesting it is an alternative spelling of "must".
According to scrabblewordsolver.com, the Collins dictionary is the only one that lists this word.
