GUADALAJARA, Mexico -- The United States and England are often described as two countries separated by a common language. So imagine the potential for confusion, curiosity and laughs around the Pan American Games, where Spanish -- in all its variations -- is the official language of about half the 42 competing nations.

"There are lots of different words, but the first ones we want to learn are the vulgarities that others use," Colombian water polo player Carlos Toro said.

Modesto Aguero, a sports commentator on Cuban television, recalls making his first visit to Mexico 35 years ago, a 20-something looking forward to a night out. He was stumped when he understood his Mexican friend to suggest the following.

BUENOS AIRES, Argentina -- One fact illustrates this bewildering Copa America: Paraguay enters Sunday's final against Uruguay without a single victory in five games.

Then there are the flops of Brazil and the Lionel Messi-led Argentina, a repeat of their disappointing exits in the 2010 World Cup when both also went out in the quarterfinals.

MEXICO CITY -- Herculez Gomez grew up in Las Vegas, so he understands the odds are against him wearing the U.S. jersey when the Americans open the World Cup against England on June 12.

Doubts about Argentina will be stronger than ever at this year's World Cup, mainly because of Diego Maradona, the coach who has struggled in almost every match to get quality play from some of the best footballers in the world.
