Foul-smelling sergeant-major? (4)
I believe the answer is:
rank
I believe this clue is a double definition.
'foul-smelling' is the first definition.
(I've seen this before)
'sergeant-major?' is the second definition.
(sergeant-major is an example)
(Other definitions for rank that I've seen before include "Foul - station" , "Not qualified to give order" , "Position; foul-smelling" , "film executive" , "Utter" .)
