Morphology

air + shaft

The meaning of 'air shaft' is directly compositional: 'air' (ventilating gas) + 'shaft' (a vertical passage) yields a passage for air. This is a standard noun-noun compound pattern and is cross-linguistically common, so a B1 learner who knows the parts will readily infer the meaning.

Etymology

Air shaft comes from the simple image of a long, narrow passage: air plus shaft, where a shaft is like a straight tube that lets fresh air move down into a building or a mine. So today air shaft means a vertical passage that brings fresh air to inner rooms or underground places.
