Some stuff in Norway, northern European (4)
I believe the answer is:
finn
'northern european' is the definition.
(I've seen this before)
'some stuff in norway' is the wordplay.
'some' says the answer is hidden in the clue (some of the parts of the word are used).
'FINN' is hidden in the letters of 'stuff in norway'.
(Other definitions for finn that I've seen before include "Trollope character" , "Twain's Huck; Trollope's Phineas" , "EU statesman" , "Northern European" , "Someone from Helsinki?" .)
