Country experiencing trouble in heart of ghetto (5)
I believe the answer is:
egypt
'country' is the definition.
(Egypt is a country)
'trouble in heart of ghetto' is the wordplay.
'trouble' becomes 'gyp' (gyp can mean bodily pain or trouble).
'in' is an insertion indicator.
'heart of' indicates the central letters.
The middle letters of 'ghetto' are 'et'.
'gyp' put into 'et' is 'EGYPT'.
'experiencing' is the link.
I am not very happy about this link. It may belong to another bit of the clue.
Can you help me to learn more?
(Other definitions for egypt that I've seen before include "Site of Sinai desert" , "Cairo's country" , "NE African republic" , "Home of the Sphinx" , "Part of Africa" .)
