From the NYT:
Wordle’s gameplay will stay the same, and answers will be drawn from the same basic dictionary of answer words, with some editorial adjustments to ensure that the game stays focused on vocabulary that’s fun, accessible, lively and varied.
The answer list will consist of five-letter words that fit those criteria, with the exception of plural forms of three- or four-letter words that end in “ES” or “S.” That is, the answer will never be FOXES or SPOTS, but it might be GEESE or FUNGI.
I’d love to ask them about past tenses ending in ED, which have been notably absent from the list of solutions to date.
