The hunting party trip that finishes in desert, mainly (5)
I believe the answer is:
egypt
This clue might be a double definition.
'the hunting party trip that finishes' is the first definition.
Although both the answer and definition are singular nouns, I don't understand how they can define each other.
'desert mainly' is the second definition.
The answer and definition can be both locations as well as being singular nouns.
Perhaps there's an association between them I don't understand?
'in' is the link.
Can you help me to learn more?
(Other definitions for egypt that I've seen before include "Cairo is its capital" , "Republic of North Africa" , "NE African republic" , "Cleopatra's country" , "North East African republic" .)
