Morphology

nonrapid + eye + movement

The phrase is compositionally analyzable—a learner who knows 'non/ not', 'rapid', 'eye' and 'movement' can infer 'eye movements that are not rapid'. However, its established technical sense as a specific sleep stage (absence of REM/dreaming) is specialized domain knowledge and not fully predictable from the literal components, so it is only partially transparent to a B1 learner.

Etymology

Nonrapid eye movement comes from a simple image: during this sleep the eyes stay still and do not make quick movements, unlike dream sleep that has 'rapid eye movements'. So the name describes the quiet part of sleep when people usually do not 'dream' and get deep rest.
