Talk: problem in Persian, for example? (8)
I believe the answer is:
chitchat
'talk' is the definition.
(chitchat is casual conversation)
'problem in persian for example?' is the wordplay.
'problem' becomes 'hitch' (I've seen this in other clues).
'in' indicates putting letters inside.
'persian for example?' becomes 'cat' (I've seen this in another clue).
'hitch' placed inside 'cat' is 'CHITCHAT'.
(Other definitions for chitchat that I've seen before include "Light social conversation" , "Gossipy talk" , "Light informal conversation" , "Informal talk" , "Gossip" .)
