Anguish at heart of alien realm (5)
I believe the answer is:
egypt
This might be a double definition.
'anguish' is the first definition.
Although both the answer and definition are singular nouns, I don't understand how one could define the other.
'heart of alien realm' is the second definition.
The answer and definition can be both locations as well as being singular nouns.
Perhaps they are linked in a way I don't understand?
'at' is the link.
Can you help me to learn more?
(Other definitions for egypt that I've seen before include "Home of the Sphinx" , "African country, site of an ancient civilization" , "Country ruled by Cleopatra" , "Luxor's country" , "Arab republic" .)
