means A long, narrow runner (or pair of them) you strap to your feet to glide over snow — and, as a verb, the act of doing so.

from Borrowed into English from Norwegian 'ski', which traces back to Old Norse 'skíð', meaning a split piece of wood, log, or stick — the same root that gives us 'shide'. Norway and the broader Scandinavian world have the oldest evidence of ski-like travel, stretching back thousands of years, so it's fitting that English simply took the Norwegian word wholesale rather than inventing its own.
