UN is a negating prefix before it is anything else, which is why it attaches to so many different stems. No third letter follows it often enough to guide a guess, so the 5 letter words starting with UN behave differently from every blend and digraph in this set.
The narrowing has to happen at the end instead. D and T close more UN words than any other letters, and Under, Until, Unfit and Unite each take a different third letter, which is why that slot divides the set so thinly.
There are 79 five letter words starting with UN. Under, Until, Units, Uncle and Unity are the strongest Wordle guesses because none of them repeat a letter. D and T close more of them than any other letters, so test the final slot early.
