Morphology

distributor + cap

The meaning is directly compositional: 'distributor' (an automotive part) combined with 'cap' (a removable cover) yields 'the cap of the distributor.' This follows a regular noun–noun compounding pattern that a B1 learner who knows both constituents can infer, and similar component+cover constructions exist cross-linguistically.

Etymology

The compound noun distributor cap is a literal name: it is the cap, like a small hat, that sits on the distributor and holds the wires that 'send' electricity to each spark plug. That's why it means the protective cover on that part of a car engine.
