Like the Valkyries (5)
I believe the answer is:
norse
'like the valkyries' 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 "Viking" , "Native to Scandinavia" , "Old European" , "Old Scandinavian tongue" , "Language - senor! (anag)" .)
