Did you know?

If you are aghast, you might look like you've just seen a ghost, or something similarly shocking. Aghast traces back to a Middle English verb, gasten, meaning "to frighten." Gasten (which also gave us ghastly, meaning "terrible or frightening") comes from gast, a Middle English spelling of the word ghost. Gast also came to be used in English as a verb meaning "to scare." That verb is now obsolete, but its spirit lives on in words spoken by the character Edmund in William Shakespeare's King Lear: "gasted by the noise I made, full suddenly he fled."
