trivia

Etymology 1

PIE word *tréyes From Latin trivia, plural of trivium (“place where three roads meet”). The term came to be used for any public place, and then for anything commonplace. Furthermore, because the beginners' course at university was called trivium, the word came to be used only for anything basic, simple and trivial.
