So about the word "witch"
I sometimes see people make claims about where the word came from, or what it really means, but here's the thing — literally no one knows for sure where it came from.
The one thing we know is that "witch" came from the Middle English "wicche," which in turn came from the Old English "wicca" (masculine) and "wicce" (feminine). That's it.
We don't know back any further.
Scholars literally disagree about where wicca and wicce come from. The roots have been lost, a lot of different ideas have been proposed, but none are certain. Like we know it's related to the Old English verb "wiccian," but that just means "to bewitch" and no one know where that came from either. The OED just says it's of "obscure origin" and just fucking gave up. Some scholars say it comes from the roots for "wise person." Others say it comes from words meaning "to bend" or "to weave." Another theory is that it just came from roots meaning "to gesture mysteriously."
Literally almost no one agrees.
So when someone tries to explain where the words wicce and wicca came from with any certainty, take a minute because one of two things is happening:
Either this person didn't do their research or they have an agenda.
Or both.
