IPA: /ˌkærəˈbiːnər/
KK: /kærəˈbiːnər/
A metal loop with a spring-loaded gate, used to connect ropes or gear in activities like climbing and mountaineering.
The climber secured his gear with a carabiner to ensure safety on the ascent.
Carabiner comes from the German word 'Karabinerhaken', where 'Karabiner' refers to a type of hook or clasp used by soldiers (from 'Karabiner', meaning a type of rifle) and 'haken' means hook. The term originally described a hook used to attach gear to a belt or harness, particularly in military contexts.
Think of a 'hook' ('haken') used to attach things securely, which helps you remember that a carabiner is a type of hook for climbing or securing gear.
