Former Italian coin (4)
I believe the answer is:
lira
'former italian coin' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for lira that I've seen before include "Former Italian currency unit" , "Old unit of Italian money" , "Turkish currency" , "Former unit of currency in Italy" , "Unit of money for 26 across" .)
