Take what's apt to help out medically (7)
I believe the answer is:
capture
'take' is the definition.
(capturing is a kind of taking)
'what's apt to help out medically' is the wordplay.
I cannot really understand how this works, but
'what's apt' could be 'apt' and 'apt' is found in the answer.
'help' could be 'cure' (curing is a kind of helping) and 'cure' is present in 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 capture that I've seen before include "Take prisoner" , "Ensnare" , "Take (eg, chess piece)" , "Seize, catch" , "Take by force" .)
