unfrivolous
Lacking playful levity
Unfrivolous describes something serious, substantive, or worthy of genuine attention—the opposite of trivial or flippant.
An unfrivolous question deserves a thoughtful answer.
An unfrivolous person doesn't waste time on meaningless pursuits.
The word often carries implicit approval, suggesting weight and purpose where frivolity might be expected.
