Titled lady, possibly from Iran (4)
I believe the answer is:
rani
'titled lady' is the definition.
'Rani' can be an answer for 'lady'. I am not sure about the 'titled' bit.
'from iran' is the wordplay.
'from' indicates anagramming the letters (the anagram comes from the same letters).
'iran' anagrammed gives 'RANI'.
'possibly' acts as a link.
Can you help me to learn more?
(Other definitions for rani that I've seen before include "Wife of a rajah" , "Raja's wife" , "Raja's queen" , "Member of royal family" , "Hindu queen or princess" .)
