Morphology

ellipsoidal = ellipsoid (semi-transparent) = ellipse + oid + al

The adjective is a regular formation from the technical noun 'ellipsoid', but the base itself is a scientific term that many learners may not know.

Etymology

Ellipsoidal comes from ellipse, which originally meant 'falling short' of a circle. Think of an ellipse as a stretched circle and an ellipsoid as that shape in three dimensions, like a rugby ball or the slightly flattened shape of Earth, so ellipsoidal means 'like an oval 3D shape'.
