BLITHESOMENESS — [Noun] The quality or state of being cheerfully lighthearted and joyous. From blithesome (from blithe, meaning "joyous, merry" + -some, a suffix forming adjectives meaning "characterized by") + -ness (a suffix forming nouns denoting a state or quality). Unlike joviality, which implies a hearty, convivial mirth, or contentedness, which denotes a placid satisfaction, blithesomeness is a quieter, self-sufficient buoyancy. It is the scent of linen snapping on a sunlit line, the effortless arc of a leaf in an updraft, or a child’s unconscious hum while at simple play—a fleeting, uncalculated affirmation that, for a moment, the weight of the world is illusory.
