The term football originally meant "a game played on one's feet" to distinguish the game (the precursor of today's many football codes) from polo, which was the game of the era. Hence "football" can be rightly applied to any sport played on foot, using a ball. The term soccer derives from "Asocciation football", possibly via the FA, or FIFA, and is used in countries where a form of football existed before soccer was made "the world game".
