Revenant is a variation of the French word Revenir or to return, it could be translated to “one who returns after death”.
Vampire lore uses the word to describe anyone who has died and risen from the grave and lives an unlife or undeath among the living.
Note not all vampires are revenants but a lot are. Not all revenants are vampires.
Zombies are also counted as Revenants.
