Greek character left at church on a road south, with fish (9)
I believe the answer is:
pilchards
'fish' is the definition.
(type of fish)
'greek character left at church on a road south' is the wordplay.
'greek character' becomes 'pi' (letter from the Greek alphabet).
'left' becomes 'l' (common abbreviation).
'at' means one lot of letters go next to another.
'church on a road south' becomes 'chards' (I can't justify this - if you can you should believe this answer much more).
'pi'+'l'+'chards'='PILCHARDS'
'with' acts as a link.
Can you help me to learn more?
(Another definition for pilchards that I've seen is " Fish".)
