Studies, having ignored one bog, requiring return around a part of South Africa (9)
I believe the answer is:
transvaal
'part of south africa' is the definition.
(I know that Transvaal is part of South Africa)
'studies having ignored one bog requiring return around a' is the wordplay.
I cannot really understand how this works, but
'one' could be 'an' (an apple is one apple) and 'an' is present in the answer.
'a' is present in the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for transvaal that I've seen before include "South African region" , "Boer republic" , "Former province of South Africa" , "old region" .)
