A fast team sport played outdoors on a large grass field. Each player carries a stick with a small net (a 'head') at the top; you catch the hard rubber ball in that net, run with it, pass it through the air, and throw it into the other team's goal. Full outdoor men's teams have ten players a side; women's teams have twelve, and there is also an indoor version with fewer players, so the number changes with the version. It is a contact sport — men's lacrosse uses helmets and pads — and it is known for being very quick, closer to ice hockey in feel than to football. The game comes from the Indigenous peoples of North America, who played it long before Europeans arrived and still regard it as more than a sport; it later became popular in Canadian and American schools and universities. In Taiwan it is uncommon, so most people will know it only from American films and TV.
