Etymology

Origin of speaker

Middle English word dating back to 1275–1325; see origin at speak, -er ¹

Explanation

A speaker is someone who delivers a speech or a device that makes sounds louder. The speaker gave a great speech but you couldn't hear it because the speaker was turned off. Speaker has a few different meanings, from the person who addresses a group, to the piece of equipment that amplifies sound to someone who is fluent in a particular language. For example, a native Spanish speaker can usually tell if someone learned the language in high school because textbooks don't always include the slang and idioms of everyday speech.
