Morphology

spheroidal = spheroid (semi-transparent) = spher + oid + al

The adjective is transparently formed from the base noun 'spheroid' with the standard suffix '-al'.

Etymology

Spheroidal comes from the Greek word sphaira meaning 'ball' and the ending -oid meaning 'like' or 'in the shape of'. You can see the same root in sphere, so spheroidal simply means 'like a ball' or almost round in shape.
