A rose by any other name....is a tulip?

Grand Slam

Baseball, Tennis, Rugby Union all use the term but for different meanings - slightly confusing if you get crossed wires, but they each exist in fairly separate circles.

Football

In Britain, it is Association Rules, in the USA it is American Rules, in Australia it is Australian Rules, many Rugby players use the word to describe their profession - in the globalised world this can at best cause confusion, at worst cause arguments or further deepen stereotypes

Is this just a derivative of popularity focusing the language, or stubbornness from the Brits?

There seems to be a lack of desire to cede the name Football and merge with the more common moniker Soccer

The reasons for the use of Football in a name range (from usage of the foot, having roots in other forms of football, or the size of the ball) but it seems in the UK every other form of Football either drops the word from its name or clarifies the difference. But no sport is called just Football, so surely all of them use this level of clarification

Association Rules Football(Soccer - coming from the aSOCc)
American Football
Australian Rules Football
Gaelic Football
Rugby League Football
Rugby Union Football

Granted, using the terms, American, Australian, and Gaelic, would cause more confusion, but surely the addition of Rules of Football allows for clarity - this would work for Association Rules/Association Football, but not the shortened Soccer (but this is already an internationally used abbreviation - which would probably develop over time for the other sports)

Surely it is time that Brits realised that they are outmoded in their usage of the word football...
