A trident /ˈtraɪdənt/ is a three-pronged spear. It is used for spear fishing and historically as a polearm.The trident is the weapon of Poseidon, or Neptune, the God of the Sea in classical mythology. The trident may occasionally be held by other marine divinities such as Tritons in classical art. Tridents are also depicted in medieval heraldry, sometimes held by a merman-Triton. In Hinduism, it is the weapon of Shiva, known as trishula (Sanskrit for "triple-spear").The word "trident" comes from the French word trident[citation needed], which in turn comes from the Latin word tridens or tridentis: tri meaning "three" and dentes meaning "teeth", referring specifically to the three prongs, or "teeth", of the weapon.[1] [Wikipedia]
