altitude sickness 
A medical condition that is often observed at high altitudes. Also known as Acute mountain sickness, or AMS.
anchor 
An arrangement of one or (usually) more pieces of gear set up to support the weight of a belay or toprope
approach 
The path or route to the start of a technical climb. Although this is generally a walk or, at most, a scramble it is occasionally as hazardous as the climb itself.
arête

ascender 
A device for ascending on a rope. One type of mechanical ascender is the jumar.
ATC 
A proprietary type of belay device. (A subtle play on fact that ATC also stands for Air traffic controller.)

B[edit]

"B"-grade 
A grading system for bouldering problems, invented by John Gill. Now largely superseded by the "V" grading system.
back-clipping

Swinging out from the wall like a door on a hinge.
belay 
To protect a climber from falling using a rope, friction, and an anchor.

A mechanical device used to create friction when belaying by putting bends in the rope. Many types of belay device 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.
