So, what actually is werewolf or lycanthropy? Is it a fact based on concrete evidences? Is it a myth, fabrication of feeble minds? Is it an exaggeration of some other things? Well, all these questions have been puzzling mankind for last 5 centuries. Though many ingenious hypotheses have been suggested as possible explanations, definite conclusion can't be drawn. Some experts have tried to observe it as purely supernatural phenomena while others have relied on scientific observations. Contradictions and debates still persist and will continue till any single theory solves the jigsaw which seems unlikely considering complexity and diversity of the topic. Nonetheless, the werewolf phenomenon has not perished yet; recent werewolf sightings are still reported. The word werewolf is most likely to derive from two old-Saxon words, wer (meaning man) and wolf. Frequently used Greek terms Lycanthropy refers to the transformation process while Lycanthrope, which is in fact synonymous to werewolf, is the afflicted person. The popular definition of werewolf or lycanthrope is a man who transforms himself or being transformed into a wolf under the influence of full moon.
