The word 'slalom' comes from which Scandinavian language?

Slalom is an alpine skiing and alpine snowboarding discipline, involving skiing between poles or gates. These are spaced more closely than those in giant slalom, super giant slalom and downhill, necessitating quicker and shorter turns. Internationally, the sport is contested at the Alpine World Ski Championships, and at the Olympic Winter Games.

The term slalom comes from the Morgedal/Seljord (a Norwegian dialect) word "slalåm": "sla", meaning slightly inclining hillside, and "låm", meaning track after skis. The inventors of modern skiing classified their trails according to their difficulty. Slalåm was a trail used in Telemark by boys and girls not yet able to try themselves on the more challenging runs.
