"Hapax" was part of the April 1st joke - I assumed it to be a one-off condition coded for that date (all of which was probably removed in a later version of the game so it may not be visible in the code, although I haven't looked), especially considering the definition of "hapax legomenon".
"Women" is plural. If anything, it shouldn't be in the Wordle list.
I have no idea regarding "began", unless it's because it's past tense.
