Morphology

lens + cap

The meaning 'a cover placed over a camera lens' is directly and transparently derived from combining 'lens' (an optical element) with 'cap' (a removable cover). The compound follows a common noun+noun composition pattern found across languages, so a B1 learner who knows both constituents would readily infer the intended protective cover meaning.

Etymology

The phrase lens cap paints a simple image: a small cap like a hat that fits over a camera lens to keep out dust and scratches. That's why today a lens cap means a removable cover used 'to protect' the lens 'when not in use'.
