One from Copenhagen (4)
I believe the answer is:
dane
'one from copenhagen' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for dane that I've seen before include "See 7 Down" , "Native of Copenhagen, for instance" , "Eg, Hamlet" , "Hamlet was one" , "Hamlet -- as described by 12 [GLOOMY]" .)
