dimension Definition

measure in one direction; specifically : one of three coordinates determining a position in space or four coordinates determining a position in space and time

one of a group of properties whose number is necessary and sufficient to determine uniquely each element of a system of usually mathematical entities (such as an aggregate of points in real or abstract space); also : a parameter or coordinate variable assigned to such a property

the number of elements in a basis of a vector space

to form to the required dimensions

to indicate the dimensions of (as on a drawing)

a dimension in addition to length, breadth, and depth; specifically : a coordinate in addition to three rectangular coordinates especially when interpreted as the time coordinate in a space-time continuum

something outside the range of ordinary experience

thickness, depth; also : a dimension that adds the effect of solidity to a two-dimensional system

a quality that confers reality or lifelikeness
