Tunisian currency (5)
I believe the answer is:
dinar
'tunisian currency' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for dinar that I've seen before include "Currency of several Arab states" , "Iraqi CURRENCY" , "Monetary unit of Algeria" , "Currency of several Arab countries" , "Monetary unit of several Arab countries" .)
