Etymology

The word "speaker" originates from Old English specan (later "speak"), meaning "to talk," combined with the agentive suffix -er, which denotes "one who does." Over time, it evolved to describe both people who address audiences and devices that produce sound. The parliamentary sense emerged in the 14th century, referring to the person who "speaks for" a deliberative body.
