Morphology

mountain + sickness

The meaning 'a condition experienced at high altitudes' is directly and predictably composed from 'mountain' (high landform) + 'sickness' (illness), so a learner who knows both words can infer it refers to illness related to mountains/altitude. This noun–noun compositional pattern is common across languages (e.g. Spanish 'mal de montaña'), making the phrase transparent to a B1 learner.

Etymology

Mountain sickness comes from the simple image of feeling unwell on a high mountain, where the air is thin and it is hard to breathe. So, it means 'feeling sick' when you climb very high and there is less oxygen.
