These are the daily letters in the New York Time Spelling Bee puzzle. The goal is to try to make as many words as possible, but every word must be at least 4 letters and must use the center letter (the one in brackets here). There is always at least one ‘pangram’, a word that uses all of the letters, as well.

I believe you can play the NYT puzzle for free up to a point, but otherwise you need a subscription to their games collection.

HTH.
