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 whereby the rope is clipped into a quickdraw such that 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 release the rope from the carabiner.[1][10]

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]

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]
A climbing move where the hips "twist" perpendicular to the wall, the inside arm is "locked" on an upper hold, the outside arm holds the body against the wall, and the feet press down to propel the body higher.
