Elgar is studied in African capital (7)
I believe the answer is:
algiers
'african capital' is the definition.
(capital of Algeria)
'elgar is studied' is the wordplay.
'elgar is' can be anagrammed to 'ALGIERS'.
But, I am not sure how the anagram is indicated.
'in' is the link.
Can you help me to learn more?
(Other definitions for algiers that I've seen before include "North African capital" , "North African port" , "N. African port" , "Capital city" , "NW African capital" .)
