Morphology

rotary + encoder

The compound is compositionally transparent: 'rotary' (relating to rotation) modifies 'encoder' (a device that converts input to codes), so a learner who knows both words can infer it is a device that encodes rotational motion or angular position. This adjective–noun composition follows regular English word-formation patterns and is cross-linguistically common, making the meaning predictable even if the term is technical.

Etymology

Rotary encoder comes from a simple picture: a turning part rotary and a reader that makes a code encoder. Imagine a wheel with marks that a sensor reads as it turns. That reading shows the shaft's exact 'position', so the name explains what the device does: it turns rotation into a code.
