Morphology

poison + gas

The compound meaning 'a toxic gas' is directly and compositionally derived from 'poison' (a harmful substance) + 'gas' (a gaseous substance), so a learner who knows both words can infer the MWE. This straightforward noun–noun compounding is common cross-linguistically and follows regular English composition patterns, making it transparent to a B1 learner.

Etymology

The noun poison gas comes from the simple image of a poison in the form of a gas. The name became common when invisible gases were used in war and could make people very sick or die, so it means 'a toxic gas used to harm or kill people'.
