IPA: /ˌkærəˈbɪnər/
KK: /ˌkærəˈbɪnɪr/
A soldier who carries a type of lightweight rifle called a carbine, often used in military or cavalry units.
The carabineer was ready for action with his carbine in hand.
Carabineer is derived from the French word 'carabinier', which comes from 'carabine' (meaning carbine, a type of firearm) and the suffix '-ier' (meaning one who). A carabineer originally referred to a soldier armed with a carbine, thus indicating a person associated with this type of weapon.
Think of a 'carabine' (a type of firearm) and remember that a 'carabineer' is someone who is associated with or carries this firearm.
