The word "rider" originates from Old English rīdere, derived from the verb rīdan ("to ride") + the agent suffix -ere. The verb "ride" itself traces back to Proto-Germanic rīdaną, meaning "to move atop or be carried." Over time, the suffix -er (from Old English -ere) became a standard way to denote a person performing an action. The secondary meaning ("additional clause") emerged metaphorically in the 17th century, likening appended legal terms to a person "riding along" with a document.
