means A persistent source of harm, trouble, or ruin — the specific thing that undoes you, again and again.

from From Old English 'bana,' meaning slayer or killer, with roots going back to a much older Germanic word for death or murderer. It once named the killer themselves, not just the harm they caused — you can still feel that lethal edge in words like 'baneful' and in old plant names like 'henbane' and 'wolfsbane,' poisons named for what they killed. Over time the word softened from 'the one who kills you' to 'the thing that keeps ruining your week,' but it never quite lost the whiff of death it started with.
