speaker

The word "speaker" is a transparent compound formed within English from the native verb "speak" and the agentive suffix "-er." The verb "speak" itself descends from the Old English sprecan, tracing back to the Proto-Germanic \sprekaną, which carried the core meaning of making a sound or uttering words. The suffix "-er," from Old English -ere, is a prolific Germanic formative for creating nouns that identify a person or instrument associated with an action. Thus, the literal and enduring logic of "speaker" is simply "one who speaks," a meaning that has seamlessly extended from a person who talks to the presiding officer of an assembly and, in the 20th century, to the electronic device that produces sound.
