==Etymology and usage== The word ski comes from the Old Norse word which means "cleft wood," "stick of wood," or "ski". In Old Norse common phrases describing skiing were fara á skíðum (to travel, move fast on skis), renna (to move swiftly) and skríða á skíðum (to stride on skis). In Norwegian this word is usually pronounced . In Swedish, another language evolved from Old Norse, the word is (plural, ; singular: ). The modern Norwegian word ski and the Swedish word skid have largely retained the Old Norse meaning in words for split firewood, wood building materials (such as bargeboards) and roundpole fence.
