Morphology

altitude + sickness

The meaning is directly compositional: 'altitude' (height above sea level) + 'sickness' (illness) yields illness caused by high altitude. This follows a common noun-noun compounding pattern and has clear cross-linguistic parallels, so a B1 learner who knows both constituents can infer the meaning.

Etymology

The term altitude sickness comes from a simple picture: altitude means height and sickness means being ill. When people climb high mountains the air gets thin and they may have headache, dizziness or nausea, so the phrase means 'being ill because of high places'.
