The quality or state of being fluid; smoothness, gracefulness, and the ability to flow or change easily.
From 'fluid' plus '-ness' (noun-forming suffix creating abstract qualities). A more poetic alternative to 'fluidity' that emphasizes the quality aspect.
While 'fluidity' is the standard scientific term, 'fluidness' sounds more literary and graceful—writers often choose 'fluidness' when describing art, movement, or emotion because it has a softer, more flowing sound itself.
