Use of the American “Soccer” for the British “Football” is not an affectation. Good try.
Ah. I see. The rules of this slagging match are clear now. When I use a Britishism, that's affectation. When you use one, we just ahistorically declare it to be American.
Actually, few people realize that “soccer” is a British term. It was coined as a contraction of “Association football” to differentiate the game from “Rubgy football” when the various flavors were codified in the mid 1800s. The two variations of football were sometimes called “the kicking game” and “the carrying game.”
You are quite correct that the word “soccer” today is an American term used to distinguish “the kicking game” from tackle football, or what the Brits call “gridiron.” However I get a kick out of soccer hipsters who cry about Americans not calling it football. The word soccer was invented by the English.
