Spice similar to nutmeg (4)
I believe the answer is:
mace
'spice similar to nutmeg' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for mace that I've seen before include "Staff of office and a spice" , "Spiked club" , "Ceremonial staff or kind of spice" , "Came to get ancient weapon" , "Staff of office for a flavouring" .)
