Etymology
Origin of trident
First recorded in 1580–90; from Latin trident- (stem of tridēns ) “having three teeth”; see tri-, dent 2
Explanation
If you’re the ancient Greek god of the sea, you’re probably already familiar with a trident, a three-pronged spear you can use to stab things. The trident, which is a spear with three points, or prongs, is often associated with the Greek god Poseidon, who used his trident to cause earthquakes and create sources of water. Mere mortals, however, are more likely to use a trident for spear fishing, or long ago, for military combat. Remember not to confuse a trident with a pitchfork, which is used mainly for lifting and tossing things.
