Wonderful Indian town? (4)
I believe the answer is:
agra
'wonderful indian town?' is the definition.
The definition suggests a singular noun which matches the answer.
This is all the clue.
Can you help me to learn more?
(Other definitions for agra that I've seen before include "Home to the Taj Mahal" , "Site of the Taj Mahal" , "Taj Mahal city" , "Taj Mahal's city" , "vicinity of mausoleum" .)
