I will wear medal in retirement (5)
I believe the answer is:
going
'retirement' is the definition.
(thesaurus)
'i will wear medal' is the wordplay.
I cannot really understand how this works, but
'i' is found in the answer.
'medal' could be 'gong' (I've seen this before) and 'gong' is found within the remaining letters.
No letters remain.
This may be the basis of clue (or it may be nonsense).
'in' acts as a link.
Can you help me to learn more?
(Other definitions for going that I've seen before include "It affects runners" , "Moving away, departing" , "fading" , "Available" , "State of turf" .)
