Etymology

The Oxford English Dictionary (OED) records that the first written use of the word football used to describe a game was in 1424 in an Act forbidding it. The first written use of the word football to describe the ball was 1486, and that the first use as a verb (hence footballing) was in 1599. For the etymology, the OED just indicates it is a compound of foot and ball.

While it is widely believed that the word football, or "foot ball", originated in reference to the action of a foot kicking a ball, this may be a false etymology. An alternative explanation has it that the word originally referred to a variety of games in medieval Europe, which were played on foot.[5] These sports were usually played by peasants, as opposed to the horse-riding sports more often enjoyed by aristocrats. This explanation is supported by the fact that the word football has always implied a wide variety of games played on foot, not just those that revolved around kicking a ball. In some cases, the word has been applied to games which involved carrying a ball and specifically banned kicking. For example, the English writer William Hone, writing in 1825 or 1826, quotes the social commentator Sir Frederick Morton Eden, regarding a game — which Hone refers to as "Foot-Ball" — played in the parish of Scone, Scotland:

The game was this: he who at any time got the ball into his hands, run [sic] with it till overtaken by one of the opposite part; and then, if he could shake himself loose from those on the opposite side who seized him, he run on; if not, he threw the ball from him, unless it was wrested from him by the other party, but no person was allowed to kick it.[6] [Emphasis added].
However, there is no conclusive evidence for either theory regarding the origins of the word.

The word "soccer" originated as an "Oxford '-er'" slang abbreviation of "association", and was popularised by a prominent English footballer, Charles Wreford-Brown. This origin is evident in the sometimes-heard variation, "soccer football."
