Definition:Pythagoreans/Trivium/Linguistic Note

Definition
The word trivium is a Latin word meaning the three ways, or place where three roads meet (that is, literally: crossroads).

As the trivium was a preliminary course of study to the quadrivium, and thereby simpler, from this root the word trivial evolved, which has a meaning in accordance with insignificant, self-evident and commonplace, and the like.
