Morphology

nimbus + cloud

The meaning is directly derivable from the constituents: 'nimbus' denotes a grey, precipitation-bearing cloud and 'cloud' denotes a visible mass of water droplets, so a B1 learner who knows both words can infer a rain-producing cloud. This straightforward noun+noun composition (even if slightly tautological) follows common cross-linguistic patterns and is therefore immediately comprehensible.

Etymology

Nimbus cloud may come from an old word nimbus meaning 'rain' or a rain cloud, so the name itself points to rain. Picture a heavy, dark cloud full of water ready to fall, and that is why nimbus cloud means a thick, dark cloud that produces rain.
