Arrow

An arrow is a fin-stabilized projectile that is launched via a bow, and usually consists of a long straight stiff shaft with stabilizers called fletchings, as well as a weighty (and usually sharp and pointed) arrowhead attached to the front end, and a slot at the rear end called the nock for engaging the bowstring.
