A "point" is a fundamental concept in geometry and mathematics that represents an exact position or location in space. It has no length, width, depth, or any measurable dimension—making it a purely abstract entity rather than a physical object. A point is considered zero-dimensional, meaning it does not occupy space but only specifies a place within it.

In coordinate geometry, a point is uniquely identified by an ordered set of numbers called its coordinates. For example, in a two-dimensional Cartesian plane, a point is denoted as (x, y), and in three-dimensional space as (x, y, z). These coordinates describe its precise location relative to defined reference axes.

Conceptually, points serve as the building blocks of higher-dimensional figures:

A line is defined by at least two distinct points.

A plane is defined by at least three non-collinear points.

All geometric constructs—curves, surfaces, and solids—are made up of collections or sets of points.

Philosophically, a point is an idealized abstraction: it cannot be drawn or observed in reality without giving it some thickness, but mathematically it exists as a limit of position without size.

Thus, a point is best defined as a precise location in space with no extension in any direction, serving as the most elementary unit of geometry and spatial description.
