The Kalahari, for example (6)
I believe the answer is:
desert
'the kalahari for example' is the definition.
(kalahari is a kind of desert)
This is all the clue.
(Other definitions for desert that I've seen before include "Uncultivated" , "Abandon in barren terrain" , "Run away from the forces; desolate" , "Arid region with little or no vegetation" , "Treacherously abandon" .)
