The term EXTERNAL WORLD can be broken down into two crossword solutions: NONEGO and NATURE. NONEGO is a philosophical concept that refers to the idea that the self is not the center of the universe, and that one's own perspective is not the only one that matters. NATURE is a broad term that encompasses all of the physical elements of the world, including plants, animals, and the environment. Together, these two terms refer to the external world outside of the individual, which includes both the physical and philosophical aspects of the universe.
