ignition coil singular

Morphology

ignition + coil

The compound is compositionally clear: 'ignition' (system that ignites the engine) + 'coil' (a wound wire) directly indicates a coil used in the ignition system, so a learner can infer it is the engine component that helps produce the spark. Although technical, the meaning follows ordinary noun-noun compounding and has clear equivalents in other languages, making it predictable for a B1 learner who knows both constituents.

Etymology

The ignition coil gets its name from two simple ideas: coil is a loop of wire and ignition means 'starting the engine'. The coil changes small battery power into a strong 'spark' that lights the fuel and starts the engine, so the name describes what it does.
