Medieval weapon; aromatic spice (4)
I believe the answer is:
mace
This clue is a double definition.
'medieval weapon' is the first definition.
(I've seen this in another clue)
'aromatic spice' is the second definition.
(I've seen this in another clue)
(Other definitions for mace that I've seen before include "Medieval weapon or kind of spice" , "Came to get ceremonial staff" , "Ceremonial staff or kind of spice" , "One of 9 [CLUBS]" , "put on the rack?" .)
