cybernetics

The term 'cybernetics' was coined in the 1940s by mathematician Norbert Wiener, who derived it from the ancient Greek word 'kybernētēs', meaning 'steersman' or 'governor'. This choice was inspired by the Greek philosopher Plato's use of the term 'kybernetikē' to describe the 'art of steering' in the context of governing people. Wiener extended this core concept of governance and feedback control—essential for a steersman to correct a ship's course—to the study of regulatory systems in animals, machines, and organizations. Thus, the modern abstract science of control and communication emerged from this literal metaphor of steering, linking biological reflexes and mechanical automation under a single theoretical framework.

Structure: cybern (steersman) + etics (science/study of) cybern: From Greek 'kybernētēs' (steersman, governor). In this word, it functions as the root meaning 'to steer' or 'to govern'. etics: A suffix derived from Greek '-etikos' (pertaining to), via Latin '-etica', used to form nouns denoting a field of study or science.
