Wow that definition is garbage, you weren’t kidding. I would define the concept of “nuance” as the idea that not everything is black and white, and that there are often shades of gray in between.

For example, the question “is paper valuable?” depends a lot on the paper. Paper money, absolutely. Blank printer paper, yes but very much less so. Scrap paper that is rotting, almost certainly not.

As a result, the answer to the question “is paper valuable?” is much more nuanced than a simple “yes” or “no” answer can provide.
