Etymology
Origin of trivial
First recorded in 1400–50; late Middle English, from Latin triviālis “belonging to the crossroads or street corner,” hence “commonplace,” equivalent to tri- “three” + vi(a) “road” + -ālis adjective suffix; see tri-, -al 1
Explanation
Something that is trivial is not important or significant, such as the trivial details you shared with me about your trip to the post office this morning. Trivial can also describe something that isn't deep or meaningful, like a trivial movie that you'll forget about after the credits roll. It comes from the Latin word trivium: tri means "three" and via is "road." So a trivium is a "place where three roads meet," meaning a crossroads — just something ordinary. So something that is trivial is not worth remembering; it just isn't important.
