I think you mean Voldemort as a name... presuming I am correct in this, I believe it is unisex. It really is a sentence with no gender implied. "Vol de Mort" is a French phrase, "mort" meaning death and "vol" meaning flight, combined to form "flight from death", referencing his fear of mortality, or "flight of death", referencing his unique ability to fly.
Original answer: Are you kidding me? Voldemort is totally male and evil and has nothing to do with feminine!!!!!!!!!
