West African left from Portugal, perhaps (8)
I believe the answer is:
liberian
'west african' is the definition.
(Liberia is a west African country)
I don't understand the rest of the clue.
Can you help me to learn more?
(Other definitions for liberian that I've seen before include "Monrovian, say" , "West African" , "One from Monrovia, say" , "Native of Monrovia" , "Nationality of citizen of Monrovia" .)
