Definition of ellipsoid in English:

ellipsoid

noun ɪˈlɪpsɔɪdəˈlɪpsɔɪd

A three-dimensional figure symmetrical about each of three perpendicular axes, whose plane sections normal to one axis are circles and all the other plane sections are ellipses.

ellipsoidal

adjective ɛlɪpˈsɔɪd(ə)lˌɛləpˈsɔɪdl

Example sentencesExamples
- Inspired by Maxwell and his mathematics, Niven turned increasingly towards the study of spherical and ellipsoidal harmonics.
- The oil-bearing fluid inclusion morphologies include spherical, oval, ellipsoidal, lath-like and irregular shapes, although there is no obvious relationship between inclusion morphology and quartz cement history.
- It forms a ‘ball or shell’, as you say, of ejected material but the shape is ellipsoidal, not spherical as you might expect.
- A primary concave parabolic mirror converges the light to one focus of a concave ellipsoidal mirror.
