Today’s idiom: an ax to grind
Meaning: to have a grudge against someone
Origin: It is unclear if this phrase came from Benjamin Franklin or Charles Miner. Both had similar stories, though Franklin’s did not use the phrase, while Miner did. One of the earliest instances of the phrase was written in 1810 in Who Will Turn the Grindstone?, which it was assumed was written by Miner (it was published anonymously). A very similar story was written in 1812, this time under Miner’s name.
