Morphology
The meaning is directly compositional: a 'horn' (a loud signaling device) that uses 'air', so a learner who knows both words can infer a horn powered by compressed air. This noun‑noun compound follows a common, cross‑linguistic pattern and is therefore immediately understandable to a B1 learner.
Etymology
Air horn comes from the simple idea of a horn that uses air to make a loud sound. So the name means 'a loud horn that pushes air', used on trucks and ships to signal people.
