Living man (9)
I believe the answer is:
incumbent
'living' is the definition.
Both the answer and definition are adjectives. Maybe you can see an association between them that I can't see?
'man' is the wordplay.
I cannot really see how this works, but
'man' could be 'bent' and 'bent' is located in 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 incumbent that I've seen before include "Person in office" , "Mandatory" , "Current holder of post" , "Currently holding an office" , "official?" .)
