Usage

What does stumper mean? A stumper is a question that’s incredibly difficult to answer—one that stumps you. As a verb, stump can mean to confuse, puzzle, or perplex completely, as in The last question on the test really stumped me. When you are stumped in this way, you are usually at a loss—you don’t know the right answer and you might not even have a guess. This sense of the word usually refers to questions or riddles, but it can also refer to a problem whose solution is unknown. Unrelatedly, the word stumper can also refer to a person who campaigns for a politician candidate. The word stump can refer to a platform for making speeches. This use isn’t common, but this sense of the word is commonly used in a figurative way to refer to the place where political campaign speeches are made, especially in the phrase on the stump, as in The senator went out on the stump to try to win re-election. Stump can also be used as a verb meaning to campaign, as in He’s stumping in Iowa today or He has endorsed the senator and will be stumping for her. The term stump speech most often refers to a speech made on a campaign tour. It most commonly refers to a speech made by the politician who’s campaigning, but it can also refer to a speech made in support of that politician—a stumper. Stumpers are known for making stump speeches, but they can also do other things to stump for the candidate they’re supporting, such as giving interviews or making appearances. Example: My nephew came up with a riddle that’s a real stumper—it took me a week to figure it out!
