means To throw or fling something with a sudden, forceful motion — or the device, loop, or strap used to hurl, carry, or support something.

from From a Germanic root meaning to wind, twist, or throw with a swinging motion — related to the Old Norse 'slyngva,' to fling. The sense fans out from that core action: the weapon you whirl, the loop of cloth that cradles a broken arm, the strap that lets you sling a bag over your shoulder. The cocktail called a 'sling' arrived later, possibly because the drink was thrown together quickly, though that connection is uncertain.
