It is probable that the Wargs of the Third Age were descended from the werewolves, as these wolves could speak, suggesting they had fëar. Another possibility is that Sauron attempted to recreate the werewolves after his return to Middle-earth, and that the Wargs were the result.
The Middle-earth werewolves were not shapeshifters like the Werewolves of European folk culture.
The name werewolf appears to have been chosen because they were in essence sentient (but evil), and thus had a status beyond that of normal wolves. The element "were-" is a Germanic term that refers to humans. It suggests a shapeshifting creature of modern-day folktales such as wererat.
