A trident is a three pronged staff or spear. The word's origin is from Latin tridens or tridentis, from tri "three" and dentes "teeth". It was used by fishermen to catch fish. As a weapon, it was also used by the retiarii, Roman gladiators, who used a net to wrap their adversary and a trident to kill him. In the southern United States, this type of spear, called a gig, is used for catching bullfrogs, flounder, and sometimes carp. This kind of fishing is referred to as gigging.
Information on real forked spears can be found in the article on the military fork.
