werewolf

The word werewolf is thought to derive from Old English wer (or were)— pronounced variously as /ˈwɛər, ˈwɪər, ˈwɜr/— and wulf. The first part, wer, translates as "man" (in the specific sense of male human, not the race of humanity generally). It has cognates in several Germanic languages including Gothic wair, Old High German wer, and Old Norse verr, as well as in other Indo-European languages, such as Sanskrit 'vira', Latin vir, Irish fear, Lithuanian vyras, and Welsh gŵr, which have the same meaning. The second half, wulf, is the ancestor of modern English "wolf"; in some cases it also had the general meaning "beast."

An alternative etymology derives the first part from Old English weri (to wear); the full form in this case would be glossed as wearer of wolf skin. Related to this interpretation is Old Norse ulfhednar, which denoted lupine equivalents of the berserker, said to wear a bearskin in battle.

Yet other sources derive the word from warg-wolf, where warg (or later werg and wero) is cognate with Old Norse vargr, meaning "rogue," "outlaw," or, euphemistically, "wolf".^[1] A Vargulf was the kind of wolf that slaughtered many members of a flock or herd but ate little of the kill. This was a serious problem for herders, who had to somehow destroy the rogue wolf before it destroyed the entire flock or herd. The term Warg was used in Old English for this kind of wolf. Possibly related is the fact that, in Norse society, an outlaw (who could be murdered with no legal repercussions and was forbidden to receive aid) was typically called vargr, or "wolf."

Other terms

The term lycanthropy, a synonym, comes from Ancient Greek lykánthropos (λυκάνθρωπος): λύκος, lýkos ("wolf") + άνθρωπος, ánthrōpos ("human").^[2] A compound of which "lyc-" derives from the Proto-Indo-European root *wlkwo-, meaning "wolf", formally denotes the "wolf - man" transformation. Lycanthropy is but one form of therianthropy, the ability to metamorphose into animals in general. The term therianthrope literally means "beast-man." The word has also been linked to the original werewolf of classical mythology, Lycaon, a king of Arcadia who, according to Ovid's Metamorphoses, was turned into a ravenous wolf in retribution for attempting to serve his own son to visiting Zeus in an attempt to disprove the god's divinity.

There is also a mental illness called lycanthropy in which a patient believes he or she is, or has transformed into, an animal and behaves accordingly. This is sometimes referred to as clinical lycanthropy to distinguish it from its use in legends. Despite its origin as a term for man-wolf transformations only, lycanthropy is used in this sense for animals of any type. This broader meaning is often used in modern fictional references, such as in roleplaying game culture.

Another ancient term for shapeshifting between any animal forms is versipellis, from which the English words turnskin and turncoat are derived.^[3] This Latin word is similar in meaning as words used for werewolves and other shapeshifters in Russian (oboroten) and Old Norse (hamrammr).

The French name for a werewolf, sometimes used in English, is loup-garou (pronounced /lugaˈru/), from the Latin noun lupus meaning wolf.^[4] The second element is thought to be from Old French garoul meaning "werewolf." This in turn is most likely from Frankish *wer-wulf meaning "man-wolf."
