Country within South Africa (7)
I believe the answer is:
lesotho
'country within south africa' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for lesotho that I've seen before include "Country entirely within South Africa" , "Trickery" , "Kingdom that was formerly Basutoland" , "Landlocked country in southern Africa" , "Kingdom surrounded by South Africa" .)
