Viking has right to pry about (5)
I believe the answer is:
norse
'viking' is the definition.
(the Vikings were a Norse people)
'right to pry about' is the wordplay.
'right' becomes 'r' (common abbreviation).
'to pry' becomes 'nose' (synonyms).
'about' is an insertion indicator.
'r' inserted into 'nose' is 'NORSE'.
'has' acts as a link.
(Other definitions for norse that I've seen before include "Relating to ancient Scandinavia" , "Family of Germanic languages spoken in Scandinavia and Iceland" , "Ancient Scandinavian language" , "These men were Vikings" , "Old Scandinavian language" .)
