Examples:

Did you know?

You’d be well within your rights to respond “Surely, you jest!” to the notion that foolscap refers to a sheet of writing paper, and also specifically to a paper size of approximately 8" x 13", similar to that of a legal pad. After all, when foolscap was first used in the 1500s, it referred to an actual fool’s cap—the oft jingling headwear worn as part of a jester’s [motley](https://www.merriam-webster.com/dictionary/motley) (a sense still used today). But we promise we do not jest. The connection between the whimsical [chapeau](https://www.merriam-webster.com/dictionary/chapeau) and the paper is attributable to the former use of a [watermark](https://www.merriam-webster.com/dictionary/watermark) depicting a fool’s cap that was used on long sheets of writing or printing paper. There are various explanations for the introduction of this watermark—including the claim that a [1648 British parliamentary group](https://www.britannica.com/topic/Rump-Parliament) substituted it for the royal arms during exceptionally turbulent times—but such explanations remain unsupported by historical evidence.
