Definitely not right to leave Nordic country (5)
I believe the answer is:
noway
'definitely not' is the definition.
I can't judge whether this defines the answer.
'right to leave nordic country' is the wordplay.
'right' becomes 'r' (common abbreviation).
'to leave' indicates named letters should be taken away.
'nordic country' becomes 'Norway' (one of the five Nordic nations).
'norway' with 'r' removed is 'NOWAY'.
Can you help me to learn more?
(Other definitions for noway that I've seen before include "Under no circumstances!" , "Absolutely not!" , "Out of the question - lacks route" .)
