non-trivial
Not easily dismissed
Non-trivial describes something requiring real effort, complexity, or significance—the opposite of easy or negligible.
In computing and mathematics, a non-trivial solution or problem is one that isn't obvious or degenerate: Implementing that feature is non-trivial.
More broadly, it signals that something shouldn't be dismissed or underestimated: The cost savings are non-trivial.
The word often appears in technical contexts where speakers want to flag genuine difficulty without overstating it.
