A werewolf is a human that can turn into a half wolf half human (and depending on who made this werewolf, it might be able to turn into a standard wolf)
A lycanthrope is a being that is like a werewolf but with a different natural animal such as a bear (werebear), or a boar (wereboar), or a tiger (weretiger), or even a dog (weredog).

On another side note there are not just werewolves but werecats and weredogs as well.
