Me, in French (3)
I believe the answer is:
'me in french' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for moi that I've seen before include "You surely don't mean me?" , "affected me" , "Daniel arap . . ., Kenyan president for 24 years" , "it's the writer being facetious" , "Me - in France" .)
