What is a likenthrop?

Answer 1

That's lypothrope

it means the ability to turn into a wolf. The word comes from the Greek legend of King Lycoan who for the mistake of offering up a human sacrifice to Zeus got changed in to a wolf.

The Greeks were not the original inhabitants of the Aegean peninsula, there were small pockets of aborigines even into classical times. One of these pockets was Arcadia which retained some cultural distinctions from the Helens. King Lycoan was one of the last of these and the legend tells of the assimilation of his culture by the Greeks.
