Ellipse vs. Ellipsis — What's the Difference?

In mathematics, an ellipse is a plane curve surrounding two focal points, such that for all points on the curve, the sum of the two distances to the focal points is a constant. As such, it generalizes a circle, which is the special type of ellipse in which the two focal points are the same.

The ellipsis ..., . . ., or (as a single glyph) …, also known informally as dot-dot-dot, is a series of (usually three) dots that indicates an intentional omission of a word, sentence, or whole section from a text without altering its original meaning.

A conic section whose plane is not parallel to the axis, base, or generatrix of the intersected cone.

The omission of a word or phrase necessary for a complete syntactical construction but not necessary for understanding.

The locus of points for which the sum of the distances from each point to two fixed points is equal.

An example of such omission.

Ellipsis.

A mark or series of marks ( ... or * * * , for example) used in writing or printing to indicate an omission, especially of letters or words.

(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. Category:en:Curves

A mark consisting of (in English) three periods, historically or more formally with spaces in between, before, and after them, " . . . ", or, more recently, a single character, "…", used to indicate that words have been omitted in a text or that they are missing or illegible, or (in mathematics) that a pattern continues (e.g., 1, ..., 4 means 1, 2, 3, 4).

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

The omission of a word or phrase that can be inferred from the context.

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.

(film) The omission of scenes in a film that do not advance the plot.

Omission. See Ellipsis.

An ellipse.

The elliptical orbit of a planet.

Omission; a figure of syntax, by which one or more words, which are obviously understood, are omitted; as, the virtues I admire, for, the virtues which I admire.

A closed plane curve resulting from the intersection of a circular cone and a plane cutting completely through it;

An ellipse.

A printing symbol, usually three periods in a row (. . .), indicating the omission of some part of a text; - used commonly in quotations, so as to suppress words not essential to the meaning. A long dash (--) and three asterisks (* * *) are sometimes used with the same meaning.

Omission or suppression of parts of words or sentences
