aston

I'm a little stuck... Click here to teach me more about this clue!

'villa site' 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 aston that I've seen before include "Area of Birmingham" , "and 20: Midlands football club" , "Premiership FC" , "part of Birmingham" , "A Birmingham university" .)

I've seen this clue in the Evening Standard.
