A device that makes sounds, electrical signals, or other inputs stronger and louder. It is commonly used with musical instruments, speakers, and audio systems.
From *amplify* plus the agent noun suffix *-er*, meaning “that which amplifies.” *Amplify* comes from Latin *amplificāre* (“to enlarge”), based on *amplus* (“large, abundant”).
An amplifier is a professional “maker-bigger”—it takes tiny signals and turns them into room-shaking sound. The same concept applies in social life: some people act as amplifiers for ideas or emotions. Technology and humans both decide what gets louder.
