What did warlock mean in old English?

The word "warlock" didn't exist in Old English. It's a later word, appearing in Middle English around the 14th century.

Here's a breakdown of its origins:

* Old Norse: The word likely stems from the Old Norse word "vargulf", which literally means "wolf-man". It was used to describe a werewolf, a creature capable of transforming into a wolf.

* Middle English: The word evolved into "werwolf" in Middle English, and then further morphed into "warlock". The change in spelling is likely due to phonetic shifts in the language.

So, while the word "warlock" itself isn't from Old English, its origins lie in the Old Norse concept of a shapeshifting, wolf-like creature. This concept ultimately connected to the later use of "warlock" to describe a male sorcerer or wizard.
