Translation:Handball is a popular sport in Europe.
Not sure if it needs more clarification, but in the US, "handball" is a completely different game, akin to racquetball, but played without racquets and using gloved hands instead. As a result, a lot of Americans reading this may think it's talking about that game instead.
What, like their football is some sort of fugby, too? Strange fellows, those Americans!
If it helps, we called this olympic handball in Ireland when I was younger. As handball in Ireland is a Gaelic game, also played in America and Canada where you hit a ball off a wall with your hand and it is played between two opponents rather than between teams
