its capital is Monrovia (7)
I believe the answer is:
liberia
'its capital is monrovia' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for liberia that I've seen before include "West African nation" , "part of Africa" , "W. African nation" , "NW African Republic" , "Monrovia's country" .)
