City is unusually blunt about answer (8)
I believe the answer is:
istanbul
'city' is the definition.
(Istanbul is an example)
'is unusually blunt about answer' is the wordplay.
'unusually' indicates an anagram.
'about' means one lot of letters goes inside another.
'answer' becomes 'a' (abbreviation eg in Q and A).
'blunt' with letters rearranged gives 'tnbul'.
'tnbul' going around 'a' is 'tanbul'.
'is'+'tanbul'='ISTANBUL'
(Other definitions for istanbul that I've seen before include "Former capital of Turkey, once Constantinople" , "Turkey's largest city" , "Turkish port city" , "Nail bust in the Turkish city" , "Take the Latin bus out to Turkey" .)
