No good wearing a hat, but one’s all thrilled (7)
I believe the answer is:
atingle
'thrilled' is the definition.
(thesaurus)
'no good wearing a hat but one's all' is the wordplay.
I cannot quite understand how this works, but
'no' could be 'n' (common abbreviation) and 'n' is located in the answer.
'good' could be 'g' (abbreviation) and 'g' is found in the answer.
'a' is within the answer.
'hat' could be 'tile' (I've seen this before) and 'tile' is found within the remaining letters.
This accounts for all the letters.
This may be the basis of clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for atingle that I've seen before include "quivering with delight?" , "shivery" , "Being excited" , "feeling prickly" , "Feeling thrilled" .)
