In the Witcher saga, lycanthropes (also known as therianthropes) refer not only to werewolves as the term is traditionally used, but to any human who is cursed during the full moon to transform either completely into an animal, or into a half-man/half-animal. Silver is also lethal to these individuals.
Lycanthropes in the series include Edit
There is a lycanthrope in the game as well, a werewolf.
Werewolf is once again only therianthrope appearing.
