Garlic bulb segment (5)
I believe the answer is:
clove
'garlic bulb segment' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for clove that I've seen before include "Spice, used whole or ground" , "Pungent spice" , "Aromatic bud" , "A spice; a garlic bulb" , "Garlic segment" .)
