Why this word is great
SPORTFULNESS — [Noun] The quality or state of being playful or inclined to amuse oneself, often with a physical or competitive edge. From sportful ("playful, inclined to sport") + -ness (noun-forming suffix indicating a state or quality). Unlike "playfulness" (which drifts on whimsy) or "mischief" (which pricks with provocation), sportfulness is the buoyant energy of bodies in motion—a wrestler's exaggerated stumble after a feigned defeat, the impromptu race down an empty street, or the way children turn a flight of stairs into an obstacle course. It is play with muscle and breath, a fleeting rebellion against the gravity of seriousness, reminding us that joy thrives in motion.
noun
- playfulness“In long winter nights it was hard to tell who enjoyed sportfulness the better, the children who romped the floor, or the parents who, with lighted countenance, looked at them.”
