A Karabiner (German), carabineer (English), caribinieri (Italian), carabinero (Spanish) were originally soldiers, often mounted, who carried carbines.
The term has died out (with carbines no longer being used?) in all but Italian, but not before it was used in German to describe the clippy thing and adopted by alpinistes, after which it gained a new ease of life with a new meaning in other languages.
Carbine was originally derived from French. The etymology is 'doubtful', but some suggest that ultimately from scarabeus (scarab).
(Newcastle Courant - Saturday 06 April 1734)
It was still being used as late as the 1940s - "In a gun battle, one
carabineer was shot dead and two others were wounded." (Gloucester Citizen - Friday 29 May 1942)
