The word "amplify" originates from Latin amplificare, combining amplus (large) and facere (to make). It entered Middle English via Old French amplifier, initially used in rhetoric to mean "expand upon." Over time, its meaning broadened to include increasing physical size, sound volume, or significance. The scientific sense (e.g., DNA amplification) emerged in the 20th century.
