noun
rappel; abseil
Technical term for descending a rope in climbing, mountaineering, or rescue work.
登山者は懸垂下降で急な岩壁を下りた。
The climber descended the steep rock face by rappelling.
Katakana loanword for 'rappel', used in the same contexts but less formal than 懸垂下降.
Compound of 懸垂 (suspension, hanging) and 下降 (descent). The exact origin is uncertain, but it likely arose as a technical translation of the Western climbing term.
