Deceive with Italian (3)
I believe the answer is:
con
I believe this is a double definition.
'deceive' is the first definition.
(I've seen this before)
'with italian' is the second definition.
('with' in Italian)
(Other definitions for con that I've seen before include "Deceive; prisoner" , "Learn; swindle" , "Study - swindle" , "Swindle after winning trust" , "Peruse carefully or swindle" .)
