1. Words that can be entered as valid guesses
2. Words that are ever used as solutions in Wordle
I think this is a great design choice (and IIRC was part of the original game). That is, Wordle doesn't want to use really obscure or uncommon slang words as the solution, as that would make the game less enjoyable (I wouldn't like it so much if the solution was a word I'd never heard of). But, when I get stuck and can't think of a word that will fit as my next guess, sometimes I just go into "mash keyboard mode" so hopefully I'll find something that will fit and get more information about the solution. More often than not something fits, and I'm usually surprised my guess is an actual word.
So, to your point, DUCKY is a valid guess but will never be an actual solution in Wordle.
This is something I noticed that improved my wordle scores a lot.
The iPhone app on the other hand includes -s plurals in its solution set, which makes for a markedly inferior game (it also has an error in its use of the yellow indication, which also impacts negatively)
Regular pasts in -ed would pretty much restrict you to four-letter verbs that are spelled with a silent E (kite ~ kited); that will be a much smaller class of words than the ones that get excluded by the "s" suffixes.
There is a weird tangential observation we can make here, which is that the plural suffix -s, the verbal suffix -s, and the verbal suffix -t all behave exactly the same way - they are ordinarily zero syllables matching the voicing of the consonant that precedes them, but when that preceding consonant is similar to the consonant of the suffix, they grow an epenthetic vowel (becoming one syllable instead of zero) and become voiced - but the -s suffixes are only spelled with their epenthetic vowel when it exists (compare mats versus masses), while the -t suffix is spelled with its vowel whether the vowel exists or not (compare mopped versus modded).
1. The words that are solutions in the current game
2. An approximately 2x size list that is the space Wordlebot uses to "play" in. Supposedly it's still common words though some seem pretty weird to even a native English speaker (and some British slang leaks through as well). For example, titer was one of Wordlebot's recommended guesses today which I correctly sort of assumed had something to do with titration but would probably never have guessed it.
3. A larger pool of words that Wordle will let you enter as guesses

I guess the article does say: > Note that these words only represent the list Wordle uses for possible solutions; there are many more guessable 5-letter words.
personally, I'd prefer a tool that included all balid guesses and wouldn't lead me so precisely to answers. there's small c cheating and big C Cheating :)
the tweaks introduced by the Times, etc., yes.
I would argue that using a dictionary is a tactic and one to better help you better play the game by introducing you to the idea of a decision tree. You can ask Wordlebot how you did and see how it approaches the problem with all the knowledge short of knowing the actual word.
If the appeal is puzzle solving, then you may want to use a dictionary as part of exploring a puzzle solving technique.
If the appeal is words, then you may enjoy plumbing the depths of what words you know, why you know them, and how they are put together.
The original Wordle word list was contained in plaintext in the game's javascript (which is what is used for this map), however I believe the current version used on NYT is using a different list. I don't know that the current set of guessable possibilities / the list of words possible to be chosen is known. I think some people have mentioned the list may have been expanded.
