Yes, Worgen Are Werewolves

[slythwolf]

They don't follow certain standard werewolf tropes, like the whole full moon thing. So what? "Werewolf", from "wer wulf", meaning "man-wolf" (where "man" stands in for "human"; we all know that shit pisses me off, but that's language for you).

Even if they didn't shapeshift, they would still be werewolves, because the worgen form is a combination of human and wolf.
