The terms used can vary between different English-speaking countries; many of the phrases described here are particular to the United States and the United Kingdom.
The technical difficulty grading system for aid climbing (both for "original" and an adapted version for "new wave"), which goes: A0, A1, A2, A3, A4, A5 and up to A6 (for "new wave"). See C-grade.[4]
A technique by which a climber descends via a fixed rope that is firmly attached to a fixed anchor point, which is also known as an "abseil station". See tat and cord.
Type of protection that dynamically changes to absorb the shape and strength of a fall; active protection is the opposite of passive protection. See cams and friends.
Part of the alpine climbing system for grading the technical difficulty of alpine climbing routes, which goes: F ("facile/easy"), PD ("peu difficile/little difficult"), AD ("assez difficile/fairly hard"), D ("difficile/difficult"), TD ("très difficile/very hard"), and ED ("extrêmement difficile/extremely difficult"); ED then goes ED1, ED2, ED3, .. etc.[4][6]
alpine knee
An awkward climbing technique where the knee is placed on the hold rather than the foot.[7]
alpine start
Starting a climb very early in the morning, generally before 5:00a.m. (and even much earlier); common to alpine climbing to avoid afternoon rockfalls and melting snow on the route, or to get firmer ice on the glacier travel to and from the route.[2]
An armchair landing
A technique in deep-water soloing for entering shallower water where the climber needs to avoid deeper hazards in the water; executed properly a 30-foot (9.1 m) fall can be absorbed in just 5 feet (1.5 m) of water.[8]
A hazardous mistake of clipping the rope into a quickdraw so the leader's end runs underneath the quickdraw as opposed to over the top of it; if the leader falls, the rope may fold directly over the gate, causing it to open and fail.[1][10]

A back-step
Stepping on a hold where the outside edge — little toe side — of the shoe touches the rock.[1][11][12]
bail
To retreat from a climb.

Big wall climbing
A long sustained sheer exposed rock climb with at least 6–10 pitches (over 300–500 metres), that typically takes over a day (if not many days), and requires the hauling of food, water, sleeping bags, and the use of portaledges.[1]

Snow bollard
A large block of rock or ice that is used as an anchor to construct a belay.

An Australian term for a metal hex-headed machine bolt that functions like a bolt but with no fixed bolt hanger; climbers attach to the carrot bolt by using a version of a rivet hanger or by attaching a removable bolt hanger plate.[24]
Type of harness that also covers the upper body to help prevent a rotation in any fall; particularly used when the climber is carrying a heavy pack, or is climbing in an area with crevasses.

direttissima
Italian for "shortest link", is the most direct route to the summit of a mountain up the fall line (e.g. the Brandler-Hasse Direttissima on the Cima Grande, Dolomites); origin of the term is often attributed to Emilio Comici who said: "I wish some day to make a route, and from the summit let fall a drop of water, and this is where my route will have gone".[36]
direct start
A new variation of an existing rock climbing route that avoids detours taken before the main line is reached due to their greater difficulty (e.g. Suprême Jumbo Love as a direct start to Jumbo Love).

drive-by
A deadpoint where one arm crosses over the other to reach a hold that is above and to the side.
drop knee
Also egyptian.
Also knee drop.
Also lolotte.
An advanced rock-climbing technique where the knee is dropped downwards to twist the hips—and the centre of gravity—closer to the rock face, thus increasing the amount of upward reach and torque available to the climber; the unique stresses on the knee can lead to serious injuries.[1][11]

eliminate
1. A bouldering move, or series of moves, where certain holds are placed "off bounds".[2]
2. A British climbing term for a route that does not take the most obvious or direct line, and instead 'eliminates' the use of other features to create its line (e.g. not allowing the climber to use a nearby crack in making their ascent).[2]
Using teams of support people (e.g. support climbers, sherpas, and/or equipment porters, etc.), and equipment (e.g. fixed rope, base camps, etc.) in helping the lead climbers reach the eventual summit; opposite of alpine style.
Also figure of four and figure-four move and yaniro

Talus rocks
An area of large rock fragments on a mountainside where the rocks are stable and not loose like scree.
talon hook
A type of three-pronged climbing hook used for securing the climber to a horizontal edge in the rock face. Each prong contains a curved hook of differing widths for securing onto respective edge sizes when aid climbing.
A big wall climbing technique where the lead climber carries an additional static rope (in addition to their dynamic climbing rope) that hangs (or "trails") behind them as they ascend; the trail rope enables the belayer to pass equipment to the leader during the ascent, and for the leader to haul up equipment as the belayer ascends.[22][61]
