Split leftover capital (5)
I believe the answer is:
quito
This could be a double definition.
'split leftover' is the first definition.
Although both the answer and definition are singular nouns, I cannot understand how they can define each other.
'capital' is the second definition.
(capital of Ecuador)
Can you help me to learn more?
(Other definitions for quito that I've seen before include "S America" , "Ecuadorian capital" , "Capital of Ecuador" , "City" .)
