prismatoid singular

Morphology

prismatoid = prism (semi-transparent) = prism + oid

Formed from 'prism' + the suffix '-oid' meaning 'like' or 'resembling'; the morphemic relation is clear but the precise technical geometric definition is specialized.

Etymology

The word prismatoid comes from prism and the ending -oid, which means 'like' or 'resembling', as in asteroid and humanoid. So a prismatoid is a solid 'like' a prism: its vertices lie in two parallel planes and the faces in those planes act as its bases.
