The quality or state of being gamesome; playfulness, sportiveness, or a naturally cheerful disposition toward fun.
Noun form derived from 'gamesome' by adding '-ness' (Old English '-nes'), a productive suffix that creates abstract nouns representing qualities or states.
The '-ness' suffix is one of English's most ancient word-building tools—adding it to 'gamesome' creates a abstract quality you can discuss philosophically, which is exactly how 18th-century writers analyzed character traits.
