Outside the United States

Outside the United States, the sport is referred to as "American football" (or a translation thereof) to differentiate it from other football codes such as association football (soccer), rugby football, Australian rules football and Gaelic football. In Australia and New Zealand the game is also known as gridiron football, or more commonly as gridiron,^[37][38] although in the United States the term gridiron refers only to the playing field itself.^[39] The term gridiron has also been used in the UK to describe the game.^[40] In much of the world, the term football is unambiguous and refers to association football (known commonly as 'soccer' in the United States).
