Ellipse vs Rhombus - What's the difference?

ellipse | rhombus |

In geometry terms the difference between ellipse and rhombus

is that ellipse is 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 while rhombus is a parallelogram having all sides of equal length. it is a square with the corners pulled so the angles are all acute.

As a verb ellipse

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