There, another one of those words that suggest there is separation in the world around us, or even between us and the world around us. But when brought back to their historic essence, words in a nature are just the names that Adam and Eve were allowed to give to things in the garden of Eden. Their offspring continued this tendency to name everything they saw, creating more and more separation of concerns. Even if you discard the biblical reference, that is exactly what development of language did over time: we simply created new labels for stuff that we discovered over time.
And of course this was a terrible thing to keep organized: because of the distributed nature of humanity, languages split apart, and different words came to be used for identical objects or concepts.
