Actor Montand (4)
I believe the answer is:
yves
'actor montand' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for yves that I've seen before include "-- Montand (French actor)" , "Frenchman maybe" , "-- Saint-Laurent, French fashion designer" , "French male name" , "Montand, Fr. actor" .)
