Country cabin in block (6)
I believe the answer is:
bhutan
'country' is the definition.
(Bhutan is an example)
'cabin in block' is the wordplay.
'cabin' becomes 'hut'.
'in' is an insertion indicator.
'block' becomes 'ban'.
'hut' put inside 'ban' is 'BHUTAN'.
(Other definitions for bhutan that I've seen before include "Country of the Himalayas" , "Bowman" , "Himalayan kingdom" , "Indian protectorate in the southeast Himalayas" , "kingdom near China" .)
