Rock Climbing Terms and Slang: A Beginner's Glossary of Climbing Terminology

Route and movement terms

Beta is information about how to climb a route or problem, such as where to put your feet or which hold to use. The crux is the hardest part of a route. A project is a route you are working on over multiple attempts. A send is a successful ascent of a route without falling or resting on the rope.

A flash means climbing a route first try with prior information, while an onsight means doing so with no prior information at all. A dyno is a dynamic move where you jump for a hold. A mantle is a move like climbing out of a swimming pool, pressing down on a hold to stand up.

Other common terms include a traverse, which means climbing sideways rather than up, and a top-out, which means finishing a problem by pulling over the top of the boulder or wall. A warm-up route is an easy climb done to prepare.

Hold and technique terms

Holds come in many types: jugs are large and easy, crimps are small edges, slopers are rounded holds with no edge, pinches are held between thumb and fingers, and pockets are holes that fit a few fingers. Each type calls for different grip strategies.

Technique words include flagging, where you extend a leg for balance, a heel hook, where you hook your heel on a hold, and a drop knee, a twisting position that brings the hips closer to the wall. Smearing means pressing your shoe on the rock without a defined hold.

There are many more hold names, such as sidepulls, underclings and gastons, which describe the direction in which you pull on the hold. Learning them helps you read a problem and talk it through with a partner.

Gear and equipment terms

A quickdraw is two carabiners joined by a short sling and used to clip the rope to protection. Protection or pro means any gear used to catch a fall. A cam is a spring-loaded device placed in cracks, and a nut is a metal wedge. A harness is the belt and leg loops you tie into.

A belay device creates friction on the rope so a belayer can catch falls and lower climbers. A crash pad is a thick foam pad for bouldering. Chalk dries your hands, and a chalk bag holds it. A rack is the collection of protection a climber carries.

A cordelette is a length of cord used to build anchors, and a runner is a sling. A cam is sometimes called a friend, after a brand name that became common slang. A rope bag or tarp keeps the rope clean.

Belay commands and safety terms

A belayer is the person who manages the rope and catches falls. Common commands include on belay, which tells the climber the belayer is ready, and climbing, which tells the belayer the climber is starting. Take means tighten the rope, slack means loosen it, and lower means the climber is ready to be lowered.

Falling is shouted to warn others. Rock, shouted loudly, warns of falling objects. Learn the specific commands your gym or partner uses and confirm them before each climb, because miscommunication is a common cause of accidents.

On belay and off belay are the most important phrases to know. Always wait for the belayer to confirm before you start climbing, and always confirm before you untie. Gyms may have additional rules, so ask staff if you are unsure.

Style and ethics terms

Top rope means the rope runs through an anchor above the climber. Lead means the climber carries the rope up and clips protection. Sport climbing uses fixed bolts, while trad climbing uses removable protection. Free climbing means using hands and feet for progress, with ropes only for safety.

Redpoint means leading a route without falling after practicing it. Pinkpoint means the same with protection pre-placed. A repeat is climbing a route again. These terms matter in logging and discussing ascents.

A tick is a record of a climb you have completed, and a tick list is your personal list. A beta spray is when someone gives you advice you did not ask for, so be gentle with newcomers and ask before sharing your beta.

Slang you might hear

A whipper is a big lead fall. Gumbie is a friendly or teasing term for a beginner. Pumped describes forearms feeling tight and full from sustained climbing. Barn door is when your body swings away from the wall like a door opening. A sandbag is a route graded softer than it feels.

Slang varies between communities and over time. Use it if you like, but do not worry if you do not know it. Most climbers are happy to explain.

Some terms mean different things in different places. A sandbag in one area might be a route that is a bit stiff, while in another it might mean a route that is wildly underrated. Ask a local if the grades seem odd.

Learning the language

The best way to learn is to climb with others and ask questions. Gyms often post glossaries, and guidebooks include sections on terms and ethics. Reading about technique and watching experienced climbers helps the words stick.

Focus on safety terms first. They matter most, and you will use them every session. The rest will follow naturally as you climb.
