Trivial refers to something of little importance or significance. It describes matters that are commonplace, insignificant, or easily achieved. A Trivial problem is one that can be solved with minimal effort, and a Trivial detail is one that can be safely ignored without affecting the larger picture.
It often contrasts with things that are serious, substantial, or meaningful. It can also describe something that is so obvious or self-evident that it requires no deep thought or investigation.
