I do not really know much about soccer.
I know a few things.  The neat thing about soccer is that only the goalkeepers are allowed to use their hands on the ball and only within the penalty area.  I use to play soccer as a kid.
Where did the sport originate?
It originated in Great Britain and spread from there!
Why do they call it football? Where did the term 'soccer' come from?
Same in Great Britain but it was referred to as association football.
That is interesting. I always get confused when I hear it referred to as football.
Same here especially since sometimes it is referred to as medieval football.  It is definitely strange that we have that name for our sport.
What else can you tell me about the sport?
The World Cup happens once every 4 yours and the game is played on a rectangular field!
