A device or person that amplifies or makes something larger, louder, or more intense; an amplifier.
From Latin amplificator (one who amplifies), using the -ator suffix meaning 'one who does' or 'a thing that does.' Amplify + -ator.
This Latin-style noun is the ancestor of our modern 'amplifier'—medieval scholars would recognize amplificator immediately, but we've shortened it to fit modern English speech patterns.
