Yank goes round about East African republic (5)
I believe the answer is:
kenya
'african republic' is the definition.
(I've seen this before)
'yank goes round about east' is the wordplay.
'goes round' indicates anagramming the letters.
'about' indicates putting letters inside.
'east' becomes 'e' (abbreviation).
'yank' anagrammed gives 'knya'.
'knya' placed around 'e' is 'KENYA'.
(Other definitions for kenya that I've seen before include "E African country" , "Land" , "Its capital is Nairobi" , "Nairobi's country" , "Republic in East Africa" .)
