Hunger no longer as you swing round it, perspiring (3)
I believe the answer is:
eat
'hunger' is the definition.
(thesaurus)
'no longer as you swing round it perspiring' is the wordplay.
I cannot quite understand how this works, but
'it' could be 't' (abbreviation. e.g. in 'tis) and 't' is present in the answer.
The remaining letters 'ea' is a valid word which might be clued in a way I don't understand.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for eat that I've seen before include "get stuck in" , "Bite, chew and swallow" , "Take food" , "Corrode" , "Do cats - bats? Do bats - cats? (Alice in Wonderland)" .)
