Naive to come down to Danish territory (9)
I believe the answer is:
greenland
'danish territory' is the definition.
The answer and definition can be both locations as well as being singular nouns.
Maybe you can see an association between them that I don't see?
'naive to come' is the wordplay.
'naive' becomes 'green' (similar in meaning).
'to' means one lot of letters go next to another.
'come' becomes 'land' (landing is a kind of coming).
'green'+'land'='GREENLAND'
'down to' is the link.
Can you help me to learn more?
(Other definitions for greenland that I've seen before include "Danish self-governing island, the world's largest" , "Englander in island owned by Denmark" , "country" , "icy mountain here?" , "Island mostly north of the Arctic circle" .)
