Morphology

rhombohedron = rhombus + hedron (semi-transparent) = rhombo + hedron

The meaning ('a solid whose faces are rhombi') follows from the geometric components, but both parts are technical combining forms unfamiliar to average learners.

Etymology

The word rhombohedron comes from the Greek parts rhomb- and -hedron, where rhomb- is the same root as rhombus and means 'diamond shape' and -hedron means 'face' or 'side'. So a rhombohedron is a solid whose faces are rhombuses, which is why its sides look slanted instead of square.
