New rose turned out to be European (5)
I believe the answer is:
norse
'be european' is the definition.
(I've seen this before)
'new rose turned out' is the wordplay.
'new' becomes 'n'.
'turned out' indicates anagramming the letters.
'rose' is an anagram of 'orse'.
'n'+'orse'='NORSE'
'to' acts as a link.
(Other definitions for norse that I've seen before include "Language - senor! (anag)" , "Family of Germanic languages spoken in Scandinavia and Iceland" , "Viking" , "Northern European" , "Old form of Norwegian" .)
