Etymology
Etymology Information

'autodyne' originates from Greek-derived elements in English: 'auto-' from Greek 'autos' meaning 'self', combined with 'dyne' (from Greek 'dynamis') meaning 'power' or 'force'.

Historical Evolution

'autodyne' is a technical coinage in English from the early 20th century, formed by combining the prefix 'auto-' and the element 'dyne' (a term later used in physics as the unit of force). It entered technical usage in radio engineering contexts.

Meaning Changes

Initially a compound meaning literally 'self-power' or 'self-force' in formation, it came to denote specifically a self-oscillating radio circuit or device used for detection or oscillation.
