Etymology: "Servos" is the plural of "servo," a clipping of "servomotor," the motor used in automatic control systems that corrects its own position by monitoring its output. The same spelling also names a quite different thing: "servo" is a clipping of "service station," with the suffix "-o" added, a usage familiar in Australian and British speech.
