Country boy with change of direction finally (5)
I believe the answer is:
niger
'country' is the definition.
(African country)
I can't explain the remainder of the clue.
Can you help me to learn more?
(Other definitions for niger that I've seen before include "River of West Africa" , "African country dominated by the Sahara, until 1969 a French colony" , "Land-locked country and river of W Africa" , "West African country, capital Niamey" , "Part of Africa" .)
