Continue stink about part being cut (7)
I believe the answer is:
prolong
'continue' is the definition.
(I know that continue is a is a kind of of prolong)
'stink about part being cut' is the wordplay.
I cannot quite understand how this works, but
'about' could be 'on' (as in a book 'on' a certain topic) and 'on' is located in the answer.
'being' could be 'pro' (pro is a kind of being) and 'pro' is found within 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 prolong that I've seen before include "Perpetuate" , "Make last" , "Have extended" , "String out" , "Lengthen in duration" .)
