ski

Imagine crisp mountain air, bright snow, and the rush of moving down a white slope. That is often the picture this word brings to mind. It can mean the winter sport of moving over snow on long, narrow runners attached to special boots. It can also mean one of those runners themselves. You can go skiing, and you wear skis on your feet.

The word comes from Old Norse and originally referred to a split piece of wood, which fits the first skis well. Most of the time, it is about snow, whether you are going downhill at a resort or moving across flat land in cross-country travel. It can also be used for moving over water while being pulled by a boat, as in water-skiing.

This word is most strongly linked with snow and winter movement. As a noun, it usually means one of the long, narrow runners worn on the feet to glide over snow. As a verb, it means to travel or move over snow on them. Many people first meet the word in downhill mountain sports, where a person turns and slides down prepared slopes, but it is also used for cross-country travel, touring, racing, and other snow-based styles.

The idea is simple but wide: a person can ski for sport, for travel, or for fun, and the skis are the tools that make that movement possible. In older times they were made of wood, and the history of the word still reflects that. Today, the word appears in everyday phrases such as ski trip, ski slope, ski boots, and ski resort. It works naturally in both casual and formal English.

The meaning also stretches beyond snow in a few related uses. In water-skiing, a person skis on the surface of the water while being pulled by a boat. In technical or descriptive contexts, the word can also name a runner-shaped part under a vehicle, sled, aircraft, or machine. Even so, for most learners, the main meanings are clear: the winter activity and the long runner used to glide over snow.
