What is wargs definition?

Wargs are fictional creatures that appear in J.R.R. Tolkien's Middle-earth universe. They are often depicted as large and powerful wolves, with heightened intelligence and an ability to communicate with each other. They are known to be loyal servants of the dark lord Sauron and his armies, and are often used as mounts by orcs and other evil beings. Despite their fearsome reputation, wargs can also be tamed and used as allies by certain characters, such as the skin-changer Beorn. In the popular film adaptations of Tolkien's works, wargs are depicted as menacing, fanged beasts with a strong sense of hierarchal structure and pack mentality.
