Silly-billy in southern Italy (3)
I believe the answer is:
nit
'silly-billy in southern italy' is the definition.
I can't tell whether this defines the answer.
'in southern italy' is the wordplay.
'in' indicates a hidden word.
'NIT' can be found hidden inside 'southern italy'.
Can you help me to learn more?
(Other definitions for nit that I've seen before include "Louse; fool" , "Muggins" , "Foolish person" , "Louse's egg - berk" , "Parasite's egg made of tin" .)
