piton

Imagine scaling a steep rock face or looking up at a sharp peak in the distance. In English, a piton can mean either a metal spike used in climbing or a pointed rock peak. In climbing, it is a small piece of metal that a climber hammers into a crack in the rock to make an anchor for ropes and other gear.

You may also see the word used for a narrow mountain top or a tall rocky point, especially in place names or travel writing. In modern climbing, removable gear is often preferred because it causes less damage to the rock, but these metal spikes are still used when other protection will not hold.

A piton has two main meanings in English. The first is a metal spike or wedge that climbers hammer into cracks in rock to create an anchor point. The second is a sharp mountain peak or rocky spire. Both meanings share the same basic idea of something pointed and striking.

In climbing, a piton is part of older and more serious styles of protection. A climber drives it into the rock with a hammer and clips rope or gear to it. Early ones were often made of iron, while modern ones are usually made of strong steel and come in different shapes for different cracks. Although many climbers now prefer "clean" gear that can be removed without scarring the rock, pitons are still used in aid climbing, on some alpine routes, and in places where other gear does not fit well.

In geography, the word is often used for a steep, pointed peak, sometimes one formed by volcanic rock. This sense appears often in the names of mountains and landmarks, especially in French-speaking regions or places influenced by French naming. If you read about a dramatic peak rising sharply above the land, that feature may be called a piton.

The word comes from French, where it can refer to a spike or a peak. That history helps explain why English uses it for both a climbing tool and a mountain shape. The exact meaning is usually easy to tell from context: if the topic is climbing gear, it means the metal spike; if the topic is landscape or travel, it means the pointed peak.
