African bishop brought in by troubled airline (8)
I believe the answer is:
liberian
'african' is the definition.
(Liberian is an example)
'bishop brought in by troubled airline' is the wordplay.
'bishop' becomes 'B' (chess abbreviation).
'brought in by' indicates putting letters inside.
'troubled' indicates an anagram.
'airline' with letters rearranged gives 'lierian'.
'b' placed within 'lierian' is 'LIBERIAN'.
(Other definitions for liberian that I've seen before include "One from Monrovia, say" , "Nationality of citizen of Monrovia" , "Native of Monrovia" , "West African" , "Monrovian, say" .)
