Food store, pub fitted in old Greek precinct (6)
I believe the answer is:
delphi
'old greek precinct' is the definition.
The definition and answer can be both locations as well as being singular nouns.
Perhaps you can see a link between them that I don't see?
'food store pub fitted in' is the wordplay.
'food store' becomes 'deli' (short for delicatessen).
'pub' becomes 'ph' (abbreviation for Public House).
'fitted in' is an insertion indicator.
'deli' placed around 'ph' is 'DELPHI'.
Can you help me to learn more?
(Other definitions for delphi that I've seen before include "Ancient Greek sanctuary dedicated to Apollo" , "Place of the famous oracle" , "Scene of ancient oracle" , "Home of the oracle on the slopes of Mount Parnassus" , "Where god used to speak" .)
