Impressed by fairy's wings, Quince had become nervous (7)
I believe the answer is:
fidgety
'nervous' is the definition.
(synonyms)
'impressed by fairy's wings quince had become' is the wordplay.
I cannot really understand how this works, but
'had' could be 'd' (in contractions e.g. 'I'd', 'you'd' etc) and 'd' is found within the answer.
'become' could be 'get' (synonyms) and 'get' is found within the answer.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for fidgety that I've seen before include "Making a fuss" , "Nervous and unable to relax" , "Agitated, restless" , "Nervously moving" .)
