Greek market place lacking the focus of a Mughal capital (4)
I believe the answer is:
agra
'mughal capital' is the definition.
The definition suggests a singular noun which matches the answer.
'greek market place lacking the focus of a' is the wordplay.
I cannot quite see how this works, but
'greek' could be 'gr' (abbreviation for Greek) and 'gr' is located in the answer.
'a' is found in the answer.
A single letter 'a' remains which might be clued in a way I don't understand.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for agra that I've seen before include "city founded in 1566" , "vicinity of mausoleum" , "City in India" , "Indian masterpiece" , "includes Taj Mahal" .)
