Ever wonder where the name “bonfire” comes from? Me either, but it ends up it is interesting.
Bonfires are typically associated with celebrations, backyard burnings, and toasting marshmallows, and although these are all good things, the bon in bonfire isn’t related to the French for “good.” Instead, bonfire actually stems from the Middle English bonefire, literally referring to a fire of bones.
