While I had kind of intuited this (I’ve developed my strategy over time to always favor the more common word when choosing among multiple possibilities), I didn’t realize some of the places where Wordle cuts its solution set. Specifically, I somehow never noticed that solutions are never s-suffixed plural, but you can clearly see it in the visualization if you try entering a word with four letters.

This is something I noticed that improved my wordle scores a lot.

First I'd heard of it. Although looking back, I've tested lots of plurals and can't recall one ever being right. Sort of degrades the game to have an unwritten rule like that.

This is an important feature in fact, as otherwise the space of possible solutions grows to include nearly all 4-letter nouns (and verbs) +'s', and this is too large. I believe that regular pasts in -ed are also excluded for the same reason.

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).

Wordle seems to favor base words generally but it doesn't seem to be as rigid about it as with plurals ending in an "s" (which I don't think I've ever seen one of).

I think the design choice is key to the game, but for a different explanation. “Be liberal in what you accept” -> don’t reject a valid but obscure word as a guess, because people who know it’s a word will be rightly annoyed that the game is kneecapping their play.

NYT's Spelling Bee game is an example of the opposite case. It's a little bit like Wordle (you're given a set of letters and need to make words), but it doesn't accept obscure words. So I'm constantly coming up with words that fit the letters nicely and get rejected. It drains away a lot of the enjoyment.

I think the NYT's argument is that allowing obscure words drains excitement from those who don't know the word. They can't get a perfect score. So they have a choice of annoying you or annoying them and they chose to play to a broad base.

Squaredle [1] accepts many obscure words as bonus words that don’t count toward the canonical maximum word score but do serve as a tiebreaker for the leaderboard.

There are actually 3 lists if you count the Wordlebot 2.0 [1] list:

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'm still sore over HUNKY.

Slangy words seem to be one area where Wordle can be all over the map where something may be a valid solution or it may not even be a valid guess.

This is why "which of the possible words is most common?" is an important question when solving.
