African grassland (7)
I believe the answer is:
savanna
'african grassland' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for savanna that I've seen before include "Grassy (African) plain" , "Open grasslands of Africa" , "Flat, tropical grassland" , "Tropical African grasslands" , "Large grassy plain with few trees" .)
