Morphology
icosahedral = icosahedron (semi-transparent) = icosa + hedr + al
The adjective is formed regularly from the technical noun 'icosahedron' with the suffix '-al', but the base term itself is specialized.
Etymology
The word icosahedral comes from Greek parts icosa- 'twenty' and -hedron 'face'. So an icosahedral object is one that has twenty faces, like a triangle has three sides.
