Morphology

altocumulus + cloud

The phrase is directly compositional: 'altocumulus' denotes a medium-altitude cloud type and 'cloud' names the atmospheric mass, so a learner who knows both constituents can infer it refers to a type of cloud at intermediate altitudes. Although 'altocumulus' is somewhat technical, the noun+noun naming pattern and the literal meanings make the overall sense predictable.

Etymology

Altocumulus cloud comes from two parts: alto meaning 'middle' and cumulus meaning 'puffy heap'. So the name paints a simple picture of many small, rounded clouds at a middle height, and that is why we use it for those mid-level, rolled clouds.
