Old name for Iran (6)
I believe the answer is:
persia
'old name for iran' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for persia that I've seen before include "Old Iran" , "Old land" , "Aspire to this old country" , "It's now known as Iran" , "Praise be to ancient Iran" .)
