That reminds me of one of the biggest IMO missing feature of Wordle: They never give a definition of the word after the game is finished! I usually do end up googling words I don't know (which is quite often) but I'm guessing I'm one of the few who goes to the trouble. I've even written to The New York Times a couple times to suggest adding a short definition at the end as I honestly feel like a ton of people could totally up their vocabulary game and it surely could be added with minimum effort (considering they even added a Discord multiplayer mode).

Is Wordle really the best vehicle for that, though? I mean, it tends towards a subset of 5-letters words the audience is more likely to know in advance, excluding a lot of the more-surprising words.

A "click to see more about why this answer fits" crossword, on the other hand...

That's a brilliant idea and now that you've mentioned it it seems like a rather glaring omission.
