A potentially hazardous mistake that can be made while lead climbing. The rope is clipped into a quickdraw such that the leader’s end runs underneath the quickdraw as opposed to over top of it. If the leader falls, the rope may fold directly over the gate causing it to open and release the rope from the carabiner.
If a climber has only two points of contact using either the right or left side of their body, the other half may swing uncontrollably out from the wall like a door on a hinge.
To protect a roped climber from falling by passing the rope through, or around, any type of friction enhancing belay device. Before belay devices were invented, the rope was simply passed around the belayer’s hips to create friction.
A mechanical device used to create friction when belaying by putting bends in the rope. Many types of belay devices exist, including ATC, grigri, Reverso, Sticht plate, eight and tuber. Some belay devices may also be used as descenders. A Munter hitch can sometimes be used instead of a belay device.
The strongest point on the harness. This is the loop you use your belay device on. You should not tie anything around the belay loop such as a daisy chain or sling. The belay loop will wear more quickly.

- Normal flag: Where the flagging foot stays on the same side (e.g. flagging with the right foot out to the right side of the body)
- Reverse inside flag: Where the flagging foot is crossed in front of the foot that is on a foot hold
- Reverse outside flag: Where the flagging foot is crossed behind the foot that is on a foot hold
- A thin slab of rock detached from the main face.
- A method of untangling a rope in which the rope is run through the climber’s hands and allowed to fall into a pile on the ground. Useful when preparing a rope for coiling, or before starting a lead climb, to ensure the rope is fed cleanly and without twists. Often called “flaking out” a rope.
To successfully and cleanly complete a climbing route on the first attempt after having received beta of some form. Also refers to an ascent of this type. For ascents on the first attempt without receiving beta see on-sight.

Mantel (abbreviation of ‘mantleshelf’)
A move used to surmount a ledge or feature in the rock in the absence of any useful holds directly above. It involves pushing down on a ledge or feature instead of pulling down. In ice climbing, a mantel is done by moving the hands from the shaft to the top of the ice tool and pushing down on the head of the tool.

To use friction on the sole of the climbing shoe, in the absence of any useful footholds.
A style of climbing where form, technical (or gymnastic) ability and strength are more emphasized over exploration, self-reliance and the exhilaration of the inherent dangers involved in the sport. Sport climbing routes tend to be well protected with pre-placed bolt-anchors and lends itself well to competitive climbing.
In indoor climbing, a hold that is not secure and spins in place when weight is applied.
A method of protection commonly used during bouldering or before the leader has placed a piece of protection. The spotter stands beneath the climber, ready to absorb the energy of a fall and direct him away from any hazards.
