“Insignificant for Trivial, or Small. Insignificant means not signifying anything, and should be used only in contrast, expressed or implied, with something that is important for what it implies. The bear’s tail may be insignificant to a naturalist tracing the animal’s descent from an earlier species, but to the rest of us, not concerned with the matter, it is merely small.”
