trivia / trivial
Why is inconsequential or useless knowledge known as trivia? The answer dates back to the medieval educational curriculum.
The seven liberal arts were broken into two courses of study. The upper level was known as the quadrivium (Latin for four way) and consisted of the mathematical sciences of arithmetic, geometry, astronomy, and music. The lower level consisted of grammar, rhetoric, and logic and was known as the trivium.
