Different Mountaineering Terms And What Do They Mean

Mountaineering, like every other sport, has its terminology and lingo. This article serves as an essential guide on different mountaineering terms and their meanings. The more you learn, the better you communicate with your climbing colleagues.

The glossary is in alphabetical order for your convenience. Apart from mountaineering, some of the terms mentioned below are also used in wall climbing and rock climbing.
