"Snore", in old Scandinavian (5)

I believe the answer is:

norse

I'm a little stuck... Click here to teach me more about this clue!

'old scandinavian' is the definition.
(I've seen this in another clue)

'snore' is the wordplay.
'snore' can be anagrammed to 'NORSE'.
Though, I am unsure how this is indicated.

'in' acts as a link.

Can you help me to learn more?

(Other definitions for norse that I've seen before include "Old form of Norwegian" , "Native to Norway" , "Old Scandinavian tongue" , "Old Scandinavian language" , "Snore (anag)" .)

I've seen this clue in the Evening Standard.
