The word "werewolf" came from Anglo-Saxon: wer meant "man," and wolf meant "wolf." Man was placed before wolf because a werewolf transformed from man to wolf. Animagus, on the other hand, emphasized changing from animal to man, which was why animal came before magus.
In non-Anglo-Saxon languages, werewolves were called lycantropes. Lykos meant wolf, while anthropos meant man. Some werewolves called themselves "lycaon," while others, as Kettleburn had said, called themselves Mooncalves. The difference was that the former were quite satisfied with their current state, while the latter hoped to use sacrifice to transform completely into either wolves or humans.
The Mooncalves believed that werewolves, like Blood Beastfolk, had been cursed. Eventually, they would become complete animals—true wolves. True wolves were no different from ordinary wolves, except that they could understand human speech.
As for those who wanted to return to human form, they observed "fasting" and refused to eat human flesh. Their situation was somewhat similar to Remus Lupin's, except they maintained their sanity through prayer, while Remus had Wolfsbane Potion to drink.
This was not entirely meaningless. A werewolf who called himself Tos retained a degree of rationality after transforming, though he was an exceptional case. The overwhelming majority of werewolves still lost their reason after transforming.
The werewolves' unusual activity had put the Ministries of Magic in every country on high alert. Yet some people in the British Ministry of Magic, led by Ludo Bagman, thought it was no big deal. Werewolves could love Quidditch too, couldn't they? Scamander had gone to the Ministry of Magic for a meeting because of this matter. He had heard from "informed sources" that Ludo Bagman had opened a betting pool for this Quidditch World Cup. Compared with his work at the Ministry, he was far more enthusiastic about gambling. Barty
