Here are the results of WG66 whose entries are cryptic clues whose answers may be reasonable first guess words for Wordle.
Luciano
Dislocated spine aches (5)
PINES; SPINE with the S dislocated; def = aches
Succint if painful clue. I might question if P is a good letter to narrow down in the first guess but it does seem to show up a lot in Wordle, and I recently guessed BLEAT and CLEAT before getting PLEAT on the sixth and last guess. Phew.
Seat in the UK involves a single issue (5)
ARISE; ARSE around I; def = issue
Good deception in both elements of the wordplay and in the definition's part of speech, as well as a consistent UK theme. ARISE would be an excellent first guess. This is my winner.
Wild bird's hacked by a couple of axes (5)
JAZZY; JAY cut by ZZ; def = wild
Tough clue partly because the Z axis is the last one to consider, never mind two of them. JAZZY would generally be a terrible first guess, but the one time it shows up as the answer, most everyone else would not get it at all, and you would be a god to them.
Duke
Bury in uncertain terrain (5)
INTER; hidden; def = bury
Good hidden clue. Guessing the answer from the definition, I first thought the IN was given and somehow uncertain meant ‘just 3/7 of’, but then hidden clues seem to be always the last thing I consider. INTER would be a good first guess.
Demonstrated stain can be re-made: that's smooth (5)
SATIN; STAIN remade; def = that’s smooth
I don’t know what ‘demonstrated’ is doing in the wordplay other than a redundancy in the anagram. SATIN would be a good first guess.
First, try and loosen up: it can tantalize (5)
TEASE; Try + EASE; def = it can tantalize
This clue works and its surface reading can vaguely apply to doing word games like crosswords and Wordle. TEASE is not the best first guess in my opinion since we don’t want to waste letters to see if the answer has two E’s before we know it even has one.
Luciano is invited to run Word Game 67.
