Bouldering and Sports Climbing Glossary: Lingo and Language

Bouldering and Sports Climbing Glossary: Lingo and Language

You may have heard a climber say something like “the pinch wants you to barn-door so you need to flag” and wondered what they were talking about or what language they were speaking. Like every sport, climbing has its own unique jargon/language. It is common for you to go out to the cliffside or climbing gym and hear fellow climbers throwing around a bunch of terms. But what do each of these terms mean and when is the proper time to use them? No worries, I got you covered! 

Here is a dictionary of climbing terms for various types of climbing (Bouldering, Top Rope, and Sports Climbing) so you know what other climbers are saying and how to join in on the conversation. 


  • Anchor: A device or method for securing a climber to the rock/wall for their safety to prevent a fall. 
  • Approach: The walk or hike to get to your designated climbing area/route. 
  • Arete: Corner of two intersecting rocks that you are able to use as a hold. An example is the corner of a climbing wall, similar to the corner of a brick building. 
  • Ascender: A mechanical device that assists climbers moving up on the rope while requiring minimal effort.  
  • ATC: A belay device that is typically comprised of two holes (sometimes one hole) and a loop at the bottom. To use the device, you feed a loop of rope through one of the holes and hook a carabiner through the rope and loop. It is one of the most common and affordable belay devices used in climbing. 
  • Auto-lock: Spring-loaded mechanism on a carabiner gate that twists and locks automatically when the carabiner gate is closed. 


  • Backclip: When you are lead climbing, you may accidentally clip the rope into the quickdraw with the belayer’s end of your rope going away from the rock instead of going toward the rock. This is unsafe and should be avoided. 
  • Backstep: Standing on a hold using the outer edge of your foot while your hips are facing away from the foothold.
  • Backup: Additional protection added to an anchor to provide more safety. 
  • Barn Door: When you swing out sideways away from the rock. Often stopped by placing one leg behind the other so your foot can catch you (flagging). For example, if you are swinging out to the right, you can prevent this by placing your left leg behind your right leg and use the left foot to prevent your body from swinging away from the wall. 
  • Belay: The set-up/action that holds a rope in place to secure the climber if they fall. The set-up includes the rope, anchors, belay device, climber and belayer. 
  • Belayer: The person that controls the rope using a belay device to minimize the distance a climber falls. This person also controls the speed of a climber descending after finishing a route to ensure the climber’s safety. 
  • Belay Loop: A loop on the front of your harness that is sewn in for you to clip in a belay device for belaying or rappelling. 
  • Belay/Rappel Device: A device where the rope passes through and is clipped to a harness with a locking carabiner. It creates friction on the rope to make a more manageable belay for both the belayer and climber.  
  • Bent-gate Carabiner: A carabiner designed for lead climbing that is used on the rope-clipping side of a quick draw. The bent gate provides a larger opening for being able to clip into the rope. 
  • Beta: Tips or suggestions given to a climber while they are working a problem/route. Example: You have a foothold to your left. 
  • Bicolor: Different patterns and colors on a climbing rope to help in finding the center quickly. 
  • Bight: A small loop or section of rope 
  • Big Wall: A large, tall rock with multi-pitches that takes several days to climb. 
  • Bivouac (Bivy): A temporary sleeping setup on the side of a wall used during a multi-day climb. 
  • Bolted Route: A Bolted route is a route that is primarily used for sport climbing and has anchors bolted into the cliff/rock wall every few feet throughout the climbing problem/route. 
  • Bolts: Circular metal expansion pieces drilled into rocks/walls to provide protection during a climb. The bolts are used to anchor the rope to the wall using quickdraws while sports climbing. 
  • Bomber or Bomb Proof: Hold or anchor that is thought to be extremely strong and steady. With it being such a good hold/anchor, you may think it is bombproof. 
  • Bouldering: Type of climbing where you do not use a rope and climb close to the ground. Most bouldering is typically done on rocks no higher than 15 feet. 
  • Brake Hand: Primary hand used to control a belay/rappel. This hand always stays on the rope and can control the speed of the rope. 
  • Burn: A term often used to indicate another attempt on a route without necessarily making it to the top.


  • Carabiner: a metal aluminum loop with a spring-loaded gate used to connect various pieces of climbing equipment. They come in many different colors and various sizes and shapes. Carabiners are most commonly seen in belaying, connecting ropes to anchors and sometimes even to secure a chalk bag around your harness. 
  • Chalk: Magnesium carbonate powder in various forms for climbers to use in order to keep their hands dry and provide a better grip during a climb. Chalk can be purchased in either a loose form or in a chalk ball. It also comes in forms ranging from very fine to chunky.  
  • Chalk Bag: A small pouch used to hold loose chalk or a chalk ball. Most commonly secured around the waist of the climber with a drawstring closure. 
  • Chalk Bucket: A large pouch or bucket that holds primarily loose chalk and is most commonly used in bouldering. 
  • Chest Harness: A harness that is used in addition to a seat harness to provide additional support for keeping the body upright in case of a fall.

  • Directional: A piece of protection placed on a route to help guide the rope and climber from swinging out on a climb with a traverse or overhang. 
  • Drag: Friction on a rope. The more protection the rope passes through, the more friction that occurs on the rope.

Did I miss anything?

There are a lot of terms specific to climbing. Some terms are more popular or well-known compared to others just depending on who you are talking to and what type of climbing discipline you are referring to. Hopefully, this is a helpful guide for learning the lingo and understanding what other climbers are talking about. Let me know if you think of any terms that should be on this list in the comments below and I will be more than happy to add them.
