Morphology

tear + gas

The meaning 'a gas that causes tearing/eye irritation' is directly and transparently derived from combining 'tear' (teardrop/crying) with 'gas' (a gaseous substance) following the common noun–noun modifier pattern. This composition is cross-linguistically common (e.g. Spanish 'gas lacrimógeno', French 'gaz lacrymogène'), so a B1 learner who knows both constituents can readily infer the meaning.

Etymology

The noun tear gas comes from a simple image: a gas that makes people cry and brings out tears. That's why today it means 'a gas used to make people cry' and is often used by police to clear crowds.
