Morphology

living + substance

The phrase 'living substance' is directly compositional: 'living' (alive) modifies 'substance' (material), yielding 'material that is alive' which matches the provided definition. This straightforward modifier + noun pattern is cross-linguistically common and would be readily understood by a B1 learner who knows both constituent words.

Etymology

Living substance comes from early scientists who looked inside cells and called the soft, moving material there living meaning 'alive' and substance meaning 'material'. They imagined a small 'jelly' that seemed alive, so the phrase came to mean 'the material that makes up a living cell'.
