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

'incur changes in old scandinavian characters' is the definition.
I can't tell whether this defines the answer.

'incur changes' is the wordplay.
'changes' indicates anagramming the letters.
'incur' anagrammed gives 'RUNIC'.

Can you help me to learn more?

(Other definitions for runic that I've seen before include "mysterious symbols" , "Inscribed with ancient symbols" , "Like mysterious characters" , "of historic letters" , "Like some old characters" .)

I've seen this clue in The Globe and Mail.
