Definition of Ellipse

1. n. An oval or oblong figure, bounded by a regular curve, which corresponds to an oblique projection of a circle, or an oblique section of a cone through its opposite sides. The greatest diameter of the ellipse is the major axis, and the least diameter is the minor axis. See Conic section, under Conic, and cf. Focus.

Definition of Ellipse

1. Noun. (geometry) A closed curve, the locus of a point such that the sum of the distances from that point to two other fixed points (called the foci of the ellipse) is constant; equivalently, the conic section that is the intersection of a cone with a plane that does not intersect the base of the cone. ¹

2. Verb. (context: grammar) To remove from a phrase a word which is grammatically needed, but which is clearly understood without having to be stated. ¹
