ellipse
n 1: a closed plane curve resulting from the intersection of a
circular cone and a plane cutting completely through it;
"the sums of the distances from the foci to any point on an
ellipse is constant" [synonym: {ellipse}, {oval}]

Ellipse \El*lipse"\ ([e^]l*l[i^]ps"), n. [Gr. 'e`lleipsis,
prop., a defect, the inclination of the ellipse to the base
of the cone being in defect when compared with that of the
side to the base: cf. F. ellipse. See {Ellipsis}.]
1. (Geom.) 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}.
[1913 Webster]

2. (Gram.) Omission. See {Ellipsis}.
