Luggage returned to a place in Greece (6)
I believe the answer is:
sparta
'in greece' is the definition.
('Sparta' is part of 'greece')
'luggage returned to a' is the wordplay.
'luggage' becomes 'traps' (I can't explain this - if you can you should believe this answer much more).
'returned' says the letters should be written in reverse.
'traps' backwards is 'spart'.
'spart'+'a'='SPARTA'
'place' is the link.
Can you help me to learn more?
(Other definitions for sparta that I've seen before include "Ancient Greek city, capital of Laconia" , "Ancient Greek city noted for tough citizens" , "in ancient Greece" , "Ancient country" , "Formerly "City" .)
