From a country in the Horn of Africa (6)
I believe the answer is:
somali
'from a country in the horn of africa' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for somali that I've seen before include "1 [GCSE]" , "native language" , "African language" , "From a country in the Horn of Africa" , "East African national" .)
