dimension dimensions

A dimension refers to a measurable aspect of space or time, typically defined by one of three spatial directions—length, width, and height—or the fourth dimension of time in physics. Dimensions are fundamental concepts used to describe the structure of physical reality and mathematical spaces.

Etymology

The word 'dimension' comes from the Old French 'dimensio', meaning measurement, derived from Latin 'dimetere' (to measure).

Explain Like I’m 5

A dimension is like a direction you can move in, such as up/down, left/right, or forward/backward - we live in three of them!
