Meaning and Definition
An automatic device that uses feedback to correct the performance of a mechanism.
Any system, technical or metaphorical, that uses a feedback loop to self-regulate and maintain a desired state or output. Also refers to servo motors and their control systems in robotics, aviation, and manufacturing.
Dialectal Variation
British vs American Usage
Differences
No significant lexical differences. Both varieties use the full term. The clipped form 'servo' is more common in informal technical speech in both regions, but slightly more prevalent in UK engineering contexts.
Connotations
Neutral technical term in both. In UK engineering, it might have slightly stronger historical associations with analogue control systems (e.g., in vintage aircraft). In the US, it may be more immediately associated with modern robotics and digital control.
Frequency
Low frequency in general language, but standard within engineering, robotics, and aviation discourse in both regions. Slightly higher relative frequency in American English due to larger robotics and aerospace industries.

Watch out
Common Mistakes When Using “servomechanism”
- Misspelling as 'servo-mechanism' (hyphen is often omitted in modern usage).
- Confusing 'servomechanism' (the entire control system) with 'servomotor' (just the motor component).
- Using it as a general synonym for any 'automated system' without the crucial element of feedback control.
FAQ
Frequently Asked Questions
No. A servomechanism is a specific type of control system that uses feedback. A robot is a machine that may incorporate many servomechanisms (e.g., in its joints) but also includes sensors, a central processor, and an end-effector.
Rarely, and only metaphorically. For example, an economist might describe a self-adjusting market as a 'social servomechanism', but this is highly specialised figurative language.
'Servo' is an informal shortening, often referring specifically to the servo motor. 'Servomechanism' is the formal, full term for the complete automatic control system, including the motor, sensor, and comparator.
Only if you are studying or working in engineering, robotics, aviation, or a related technical field. For general English, it is a very low-frequency, specialised term.
An automatic device that uses feedback to correct the performance of a mechanism.
Servomechanism is usually technical in register.
Servomechanism: in British English it is pronounced /ˈsɜːvəʊˌmɛkənɪz(ə)m/, and in American English it is pronounced /ˈsɜːrvoʊˌmɛkəˌnɪzəm/. Tap the audio buttons above to hear it.
Phrases
Idioms & Phrases
- “The economy acts as a giant servomechanism (metaphorical use).”
Learning
Memory Aids
Mnemonic
Think of a SERVant MECHANISM: a mechanical 'servant' that automatically corrects its master's (the main system's) actions based on feedback.
Conceptual Metaphor
A SLAVE/SERVANT (the 'servo-') that automatically corrects and adjusts, ensuring the MASTER'S (the main system's) commands are followed precisely. Also, a BRAIN for a machine limb, constantly sensing and adjusting movement.
