It would be slightly interesting to read a fic in which Naming was a mechanism of magic, and Voldemort chose that specific name for very good reasons. Reasons which explained why people feared the name. Maybe he stole the Grim Reaper's power for his very own, somehow becoming Master of Death or Flight from Death or something similar, something involving an actual title with power invested into it. Neat thoughts in this area, easy for the picking. French is kind of a silly language for it, of course.
