Deli to accept parking hard in historic city (6)
I believe the answer is:
delphi
'historic city' is the definition.
'Delphi' can be an answer for 'city' (Delphi is an example). I am unsure of the 'historic' bit.
'deli to accept parking hard' is the wordplay.
'to accept' means one lot of letters goes inside another.
'parking' becomes 'p' (abbreviation on road signs).
'hard' becomes 'h' (abbreviation used in pencil classifications).
'p'+'h'='ph'
'deli' placed around 'ph' is 'DELPHI'.
'in' acts as a link.
Can you help me to learn more?
(Other definitions for delphi that I've seen before include "Scene of ancient oracle" , "'In Greek mythology, the site of the oracle (6)'" , "Place of the famous oracle" , "Greek site of Apollo's most famous oracle" , "Old Greek city" .)
