Sand blasted in Greek city (6)
I believe the answer is:
gdansk
'city' is the definition.
(Gdansk is an example)
'sand blasted in greek' is the wordplay.
'blasted' indicates an anagram.
'in' indicates putting letters inside.
'greek' becomes 'gk'.
'sand' anagrammed gives 'dans'.
'dans' put within 'gk' is 'GDANSK'.
(Other definitions for gdansk that I've seen before include "Polish city on the Baltic" , "Polish coastal city" , "It was once called Danzig" , "Major Polish port" , "Polish town" .)
