Like Vikings (5)
I believe the answer is:
norse
'like vikings' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for norse that I've seen before include "Family of Germanic languages spoken in Scandinavia and Iceland" , "Relating to ancient Scandinavian" , "Native to Norway" , "Ancient Scandinavian language" , "Relating to Norway" .)
