coordinate - One member of a tuple of numbers which defines the position of a point in some space. Commonly used coordinate systems have as many coordinates as their are dimensions in the space, e.g. a pair for two dimensions. The most common coordinate system is Cartesian coordinates, probably followed by polar coordinates.
