Scandinavian wearing no ensemble (9)
I believe the answer is:
norwegian
'scandinavian' is the definition.
(I know that Norwegian is a type of scandinavian)
'wearing no ensemble' is the wordplay.
'ensemble' indicates anagramming the letters.
'wearing'+'no'='wearingno'
'wearingno' is an anagram of 'NORWEGIAN'.
(Other definitions for norwegian that I've seen before include "Nationality of citizen of Oslo" , "Foreigner" , "One may live overseas" , "European" , "Scandinavian language" .)
