Morphology

light-emitting + diode

The phrase is fully compositional: 'light-emitting' means emitting light and 'diode' refers to an electronic device that permits current in one direction, so the combined meaning is simply 'a diode that emits light.' This follows standard English compound noun formation and is predictable for learners who know the constituent words, despite the technical register.

Etymology

The name light-emitting diode comes from a simple idea: a small part called a diode gives out light, so the words light and emitting describe what it does. That's why these devices are called 'LEDs' and are used as small lights and bright screens today.
