The quality, state, or characteristic of being directed, oriented, or moving toward a lower level or downward position.
From 'downward' plus the abstract noun suffix '-ness.' A philosophical or descriptive term for the inherent property of downward direction or orientation.
This word is rare because we don't usually need to name the *quality* of moving down—it's self-evident. When words feel unnecessary, they often disappear from living language.
