Raise a stink? (4)
I believe the answer is:
reek
'raise a stink?' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for reek that I've seen before include "Smell foully" , "Smell, like a Kerry mountain?" , "Smell strongly" , "'Stink, stench (4)'" , "Smell to high heaven" .)
