Final answer:
A 'triviality' is something small, unimportant, or insignificant. It is used to label matters that do not have significant impact or importance. Walt Whitman's perspective on the value of trivial things offers a reflective insight into this definition.
Step-by-step explanation:
A "triviality" can be defined as a small, unimportant, or insignificant matter. This term is often used to describe something that does not have much impact on the larger scheme of things or is of minor importance.
When Walt Whitman wrote, "The insignificant is as big to me as any," in his poetry, he touched upon the philosophical idea that all things, regardless of their perceived importance, hold value. In this context, even trivialities have their place in the world, suggesting a deeper reflection on the worth of small things.
