Morphology

dispersion + medium

The compound's meaning is directly compositional: 'dispersion' refers to particles being spread or dispersed and 'medium' denotes the substance or environment that carries/supports something, so together they denote the substance in which particles are dispersed. Although the term is technical, the semantic combination follows a transparent noun–noun pattern common across languages, so a B1 learner who knows both constituents can infer the meaning.

Etymology

The noun dispersion medium comes from the image of tiny particles spread through a liquid or a gas, where the medium is the liquid or air that 'carries' the dispersion of those particles. So, it means the substance 'in which particles are dispersed' today.
