Morphology

dodecahedron = hedron (transparent) = dodeca + hedron

The word is a direct combination of the Greek numeral prefix 'dodeca-' (twelve) and '-hedron' (face/solid), yielding 'twelve-faced solid'; the formation is compositionally clear though the morphemes are technical.

Etymology

The word dodecahedron comes from Greek parts dodeca- meaning 'twelve', like a 'dozen', and -hedron meaning 'face' or 'seat'. So a dodecahedron is literally 'twelve-faced', which is why it is a solid with twelve flat faces.
