Some kind of a nut (5)
I believe the answer is:
betel
'some kind of a nut' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for betel that I've seen before include "Dried leaf of a plant chewed in Asia as a mild stimulant" , "leaves to chew" , "climbing plant" , "Plant leaf chewed in the East" , "Palm with nuts for chewing" .)
