When I noticed that Wordle's list of potential answers had ARISE but not BOXED, I figured that it only used "root" words: single number, present tense, etc. But WRUNG was an answer. And now I peek at the list and see AROSE could be an answer. So… maybe non-root words are OK if their grammatical ending is, uhm, interesting? Maybe Wordle's author thought "the game won't be interesting if too many words end in -ED" and removed just those words but left in AROSE and WRUNG and other such?
I'd figured "no plurals" but FUNGI and GEESE are on the list. Maybe it's just "no plurals that end in -S"?
