Russian perhaps good at Scandinavian? (4)

'russian perhaps' is the definition.
I don't know anything about this answer so I cannot judge whether it can be defined by this definition.

'good at scandinavian?' is the wordplay.
I cannot quite understand how this works, but
'good' could be 'g' (abbreviation) and 'g' is found in the answer.
The remaining letters 'ole' is a valid word which might be clued in a way I don't see.
This may be the basis of clue (or it may be nonsense).

Can you help me to learn more?
