Check out some villas in town (7)
I believe the answer is:
seville
'town' is the definition.
The definition and answer can be both locations as well as being singular nouns.
Maybe you can see a link between them that I can't see?
'check out some villas in' is the wordplay.
'check out' becomes 'see' (I've seen this in another clue).
'some villas' becomes 'vill' (I can't justify this - if you can you should believe this answer much more).
'in' indicates putting letters inside.
'see' enclosing 'vill' is 'SEVILLE'.
Can you help me to learn more?
(Other definitions for seville that I've seen before include "Spanish city is level" , "Whence Rossini's barber" , "Capital of Andalusia" , "city taken by Moors" , "Spanish city; orange type" .)
