Country star taking in American prosecutor (5)
I believe the answer is:
sudan
'country' is the definition.
(Sudan is an example)
'star taking in american prosecutor' is the wordplay.
'star' becomes 'sun' (the Sun is a star).
'taking in' is an insertion indicator.
'american prosecutor' becomes 'da' (District Attorney. I am not sure about the 'american' bit.).
'sun' enclosing 'da' is 'SUDAN'.
Can you help me to learn more?
(Other definitions for sudan that I've seen before include "Country W. of Ethiopia" , "African nation" , "Home for many Arabs" , "NE African country, capital Khartoum" , "Country in NE Africa, capital Khartoum" .)
