Like ancient Scandinavia, and not the Kent area (5)
I believe the answer is:
norse
'like ancient scandinavia' is the definition.
Although both the answer and definition are singular nouns, I can't understand how they can define each other.
'and not the kent area' is the wordplay.
'and not' becomes 'nor' ('nor' means 'and also not').
'the kent area' becomes 'se' (Kent is in the South East of England).
'nor'+'se'='NORSE'
Can you help me to learn more?
(Other definitions for norse that I've seen before include "Language - senor! (anag)" , "Native to Norway" , "Old European" , "Old form of Norwegian" , "These men were Vikings" .)
