Morphology

critical + mass

Combining 'critical' (a point where properties change or a tipping point) with 'mass' (an amount) transparently yields the idea of a minimum or threshold quantity needed for a change to occur, a sense that is cross-linguistically common and likely inferable by a B1 learner who knows both words. However, the specific technical meaning referring to fissile material and sustaining a nuclear chain reaction is specialized domain knowledge, so the expression is only partially predictable from the constituents.

Etymology

Critical mass comes from science: it originally meant the smallest amount of material — the mass — that becomes critical so a chain reaction keeps going. That's why we now use critical mass to mean the 'minimum size' or number needed for something to start or keep going.
