Brit.

/ˈbeɪs dʒʌmp/, U.S.

/ˈbeɪs ˌdʒəmp/

Forms: 1900s– BASE jump, 1900s– B.A.S.E. jump, 1900s– Base jump, 1900s– base jump.

Origin: Formed within English, by compounding. Etymons: English BASE , jump n.¹

Etymology: < BASE, acronym ( < the initial letters of Building, Antenna-tower, Span, Earth (see quot. 1981¹), punningly after base n.¹) + jump n.¹ In later use often with the first element reinterpreted as base n.¹, as shown by the increasing frequency of the (lower-case) form base.Base jumping was pioneered as an organized sport in the late 1970s and early 1980s by an informal group of four jumpers led by Carl Boenish (1941–84), U.S. skydiver and cinematographer; the other members were his wife Jean Boenish, and friends Phil Smith and Phil Mayfield. Together they coined the acronym BASE. Compare:1981 Texas Monthly Dec. 294/3 BASE..was an acronym derived from the categories of things to be jumped from—buildings, antennas (and other towers), spans (bridges), and earth formations.1981 Texas Monthly Dec. 299/1 They began to see a pattern in the jumps they were making. After playing with several combinations and acronyms, Jean Boenish and Phil Smith came up with BASE. In addition to covering every conceivable type of fixed-object jumping, the acronym also connoted something that was stationary. The group decided that from then on they would refer to what they were doing as BASE jumping and that those who completed jumps in all four categories would be called BASE jumpers.

Originally U.S.

A parachute jump from a fixed point, typically a high building, cliff, or mountainside, rather than an aircraft.Base jumpers receive numbers (ordered sequentially) when they have jumped from each of the four types of point.
