Morphology

ellipsoid = ellipse (transparent) = ellipse + oid

Clear combination of the base 'ellipse' and the productive suffix '-oid' meaning 'like or resembling an ellipse'.

Etymology

Ellipsoid comes from ellipse and the ending -oid, which means 'like' or 'form', just like in asteroid or humanoid. So an ellipsoid is a three-dimensional 'ellipse-like' shape — a stretched or squashed sphere that people often use to model the Earth.
