Morphology
The phrase is compositionally built from 'clean' + 'room', so a B1 learner who knows both words will infer it refers to a room that is clean. However, the MWE denotes a technical, specialized controlled‑contamination environment (often written as the single word 'cleanroom'), a narrower and domain‑specific sense not fully predictable from everyday 'clean', so full understanding requires extra knowledge.
Etymology
Clean room comes from the idea of a clean room where even tiny dust and particles are kept out and people wear special suits to avoid bringing in dirt. That's why it means 'a room kept free of dust and tiny particles for sensitive work'.
