Djibouti language (6)
I believe the answer is:
somali
'djibouti language' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for somali that I've seen before include "Native of East African state" , "Eg, native of Mogadishu" , "1 [GCSE]" , "From a country in the Horn of Africa" , "From a part of northeast Africa" .)
