Definition

"Ellipsoid" refers to a three-dimensional shape where all plane sections are either ellipses or circles. Imagine a stretched or squashed sphere. It's the 3D version of an ellipse. It's similar to a spheroid but more general. Unlike a sphere, it has varying diameters. It's used in math, science, and engineering.

Etymology

The term 'ellipsoid' combines 'ellipse' (from the Greek 'elleipsis,' meaning 'falling short') and '-oid' (meaning 'resembling'). So, it essentially means 'resembling an ellipse.' It's a composite word combining two concepts. It's a more complex shape than a simple sphere.
