Signs off, indicating everything is most wonderful? (3,3,4)
I believe the answer is:
all the best
'most wonderful?' is the definition.
Both the answer and definition are superlative adjectives.
Perhaps you can see a link between them that I don't see?
'signs off indicating everything is' is the wordplay.
I cannot really see how this works, but
'everything' could be 'all' (all things) and 'all' is present in the answer.
'is' could be 'be' and 'be' is present in the answer.
'signs' could be 'hes' (he is a kind of sign) and 'hes' is located in the leftover letters.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for all the best that I've seen before include "A goodwill message" , "every member of the elite?" , "Pick of the bunch" , "Good health!" , "flower, every bit of it?" .)
