单词 ellipse
释义
ellipse
(once / 2401 pages)
n

An ellipse is a closed-plane curve that results from the intersection of a plane cutting through a cone. In other words, it’s an oval.
This is a word you'll probably see in geometry class, though it's a shape you can find all over the place. An ellipse is a closed curve that never made it around to a circle. If one thing travels around another in the shape of an ellipse — like the earth around the sun — it has an elliptical orbit. The plural for both ellipse and ellipsis is ellipses — so be careful not to mix up your ovals with your dots.
WORD FAMILY
ellipse: ellipsoid, elliptic, elliptical+/ellipsoid: ellipsoidal, ellipsoids/elliptic: elliptically, ellipticity
