the.com/coven

means A gathering or secret society of witches, or loosely, any tight-knit group that meets with a shared, often covert, purpose.

from Traces back to the same root as 'convent' — the Latin 'convenire,' meaning 'to come together.' It entered English through Old French as 'covine,' originally just meaning a group or band of people, with no occult connotation at all. It wasn't until the word landed in Scots, especially through witch-trial records and confessions (often extracted under torture), that 'coven' narrowed specifically to mean a gathering of witches — traditionally said to number thirteen, though that detail owes more to legend than to any verified historical count.
