Etymology

Origin of bane

First recorded before 1000; Middle English; Old English bana “slayer”; cognate with Old Norse bani “death, murderer,” Old Frisian bona “murder,” Old Saxon bano “murderer,” Old High German bano “slayer,” bana “death”; akin to Armenian ǰnǰel “to destroy,” Greek theínein “to strike,” Latin -fendere “to strike,” Persian zahr “poison,” Polish gonić “to pursue,” Sanskrit hánti “to strike”

Explanation

The noun bane refers to anything that is a cause of harm, ruin, or death. But we often use it for things that aren't that bad, just feel like it. You might say mosquitoes are the bane of your existence. The source of this word is Middle and Old English bana, meaning "destroyer, murderer." The now obsolete meaning of "deadly poison" is seen in the names of poisonous plants such as wolfsbane and henbane. Although "bane of my existence" is a commonly heard phrase, there's something deliciously archaic about the word bane. It conjures up villages preyed upon by dragons, or witches adding one bane or another to a steaming kettle.
