From Bonn (6)
I believe the answer is:
german
'from bonn' is the definition.
(I know that Germany is a country)
This is the entire clue.
(Other definitions for german that I've seen before include "Rang me up about the nationality" , "Proper name for 2" , "Hamburger, perhaps" , "Manger (anag.)" , "Goethe's language" .)
