Amazon country? (2,4,4)

Ross

I believe the answer is:

no mans land

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

This might be a double definition.

'amazon' is the first definition.
Although both the answer and definition are singular nouns, I cannot see how they can define each other.

'country?' is the second definition.
(I have seen 'Female country' mean 'no mans land' so perhaps 'country' could also mean 'no mans land')

Can you help me to learn more?

(Other definitions for no mans land that I've seen before include "Female country" , "dangerous place" , "part of battlefield" , "unclaimed area" , "Troops couldn't take it" .)

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