This way for the fjords (3)
I believe the answer is:
nor
'this' is the definition.
I know nothing about this answer so I cannot judge whether it can be defined by this definition.
'way for the fjords' is the wordplay.
'way' becomes 'n' (Compass direction - North).
'for' is a charade indicator (letters next to each other).
'the fjords' becomes 'or' (I can't justify this - if you can you should give a lot more credence to this answer).
'n'+'or'='NOR'
Can you help me to learn more?
(Other definitions for nor that I've seen before include "Common conjunction, goes with neither" , "Neither one ... the other" , "Link word" , "Negative conjunction" , "Neither pairing" .)
