ümargune

ümargune is an Estonian adjective meaning round. It describes objects or shapes that are circular or spherical in form. The word is derived from the Estonian word "ring," which also means circle or ring.

In geometry, ümargune refers to a circle, a shape in a plane where all points are equidistant from a central point. It can also describe a sphere, a three-dimensional object where all points on the surface are equidistant from the center.

Examples of things that can be described as ümargune include a ball, a coin, a plate, the sun, or the moon. It is a fundamental descriptor in everyday language and in technical contexts like mathematics and physics. The concept of roundness is universal and appears in many languages with similar terms.
