Etymology
The word 'servo' is a direct clipping of the longer technical term 'servomechanism'. This longer term was coined in the early 20th century, combining 'servo-' (from Latin servus, meaning 'slave') with 'mechanism'. The core concept is of a device that acts as a 'slave' or obedient follower to a control signal, amplifying its power to perform precise work. Thus, the literal idea of a subservient worker evolved into the modern technical meaning of an automated control component that faithfully executes commands from a master controller.
Analysis
Structure: serv (to serve, to keep) + o (suffix)
'serv' originates from Latin servus (slave, servant), indicating a role of following commands or performing work. The suffix '-o' is a common English suffix used to form nouns, often from technical or shortened forms.
Examples
The robotic arm uses a servo to achieve precise rotational movement.
He adjusted the servo to correct the steering on the model airplane.
Modern aircraft rely on fly-by-wire systems with multiple servos to control the flight surfaces.
