Wastes answer on awards (9)
I believe the answer is:
atrophies
'wastes' is the definition.
The definition and answer can be both related to bodily activities as well as being verbs in their -s form.
Perhaps there's a link between them I don't understand?
'answer on awards' is the wordplay.
'answer on' becomes 'a' (abbreviation eg in Q and A. I am not sure about the 'on' bit.).
'awards' becomes 'trophies' (trophy is a kind of award).
'a'+'trophies'='ATROPHIES'
Can you help me to learn more?
(Another definition for atrophies that I've seen is " Withers".)
