In classical geometry, a **point** is an entity that has no extent.
In the modern set theoretic approach to topology, this is formalised as: a **point** in a space `X` is simply an element of the set `X`.

In navigation, especially at sea, a **point** is defined as one eighth of a right angle, and therefore equals exactly 11.25 degrees. For example, a bearing of northwest by north differs by one point from a northwest bearing, and by a point from a north-northwest one.

In typography, a **point** is approximately 1/72 inch; on computer displays it is often the height of one or four pixels.

In sports and games, a **point** is a unit of scoring.

A **point** on a railroad is also called a railroad switch.
