a football field, so called for its markings.

Another term for the playing surface of a football field, more specifically the pattern created by the white lines on said surface. These lines were first introduced on football fields in 1882 for a college game. Because of the pattern created by the lines on the field, the field became known as a "gridiron", the word "grid" representing the geometric pattern of the lines, and "iron" to represent a game which required great physical strength.

Just another term for the football field.
