Certainly not a utopian land (5-5)
I believe the answer is:
never-never
'land' is the definition.
Both the definition and answer are singular nouns.
Maybe you can see an association between them that I don't see?
I cannot understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for never-never that I've seen before include "credit facility" , "Easy terms" , "Hire-purchase" .)
