Etymology

Middle EnglishEnglish

Pad has been in English since Middle English. The noun first referred to a soft flat piece placed under, over, or inside something. From that physical idea, English later extended the word to a writing pad, the broad leaf of a water plant, and a landing pad. The verb grew from the noun, first meaning to add padding and later also taking figurative uses such as padding a bill or report with extra material.
