Northern arbour’s transplanted in old negative? (10)
I believe the answer is:
bangladesh
'negative?' is the definition.
Although both the answer and definition are singular nouns, I cannot see how they can define each other.
I don't understand the rest of the clue.
Can you help me to learn more?
(Other definitions for bangladesh that I've seen before include "Bag handles (anag) - Commonwealth country" , "Asian country, capital Dhaka" , "Latest Test-cricket country" , "tourists, this year" .)
