The word werewolf derived from from the Anglo-Saxon words wer, meaning "man," and wolf, "wolf." Severus Snape mentioned this fact during a lesson on werewolves he gave to third-year Defence Against the Dark Arts students while substituting for the indisposed Remus Lupin in 1993.
The Pensieve kept in the headmaster's office at Hogwarts School of Witchcraft and Wizardry and used by headmasters was made of "ornately" carved stone engraved with modified Saxon runes. This proved that the device was ancient and pre-dated the founding of the school circa 993 A.D..
