More masculine merchant (7)
I believe the answer is:
butcher
I believe this clue is a double definition.
'more masculine' is the first definition.
('butch' can be similar in meaning to 'masculine')
'merchant' is the second definition.
(I know that butcher is a type of merchant)
(Other definitions for butcher that I've seen before include "Purveyor of meats" , "more manly" , "Killer" , "One sells meat" , "Less like lamb" .)
