Surface Forms

paraboloid singular
paraboloids plural

Morphology

paraboloid = parabola (transparent) = parabola + oid

Formed by the noun 'parabola' plus the productive suffix '-oid' meaning 'having the form of', so the meaning is directly derived from the base term.

Etymology

Paraboloid comes from parabola, meaning a 'curved shape', and the ending -oid, meaning 'like'. So a paraboloid is a three-dimensional form 'like' a parabola — imagine a bowl or a satellite dish that focuses signals, which explains the name.
