Where the Mafia originated Cicely said (6)
I believe the answer is:
sicily
'where the mafia originated cicely said' is the definition.
The answer is a location as well as being a singular noun. This is suggested by the definition.
This is all the clue.
Can you help me to learn more?
(Other definitions for sicily that I've seen before include "Large Italian island" , "Italian island, capital Palermo" , "Large Mediterranean island off Italy" , "Etna's island" , "Palermo's island" .)
