Restyling at shop that's the talk of Afghanistan (6)
I believe the answer is:
pashto
'talk of afghanistan' is the definition.
The definition and answer can be both related to communication as well as being singular nouns.
Perhaps you can see a link between them that I don't see?
'restyling at shop that's' is the wordplay.
'at shop' anagrams to 'PASHTO'.
Though, I'm not sure how the anagram is indicated.
'the' acts as a link.
Can you help me to learn more?
(Other definitions for pashto that I've seen before include "Afghan" , "language follows!" , "hear this from Afghanistan" , "Iranian language spoken in Afghanistan and Pakistan" .)
