The quality or state of being decent; propriety, respectability, or a reasonable level of acceptability.
From the adjective decent with the noun-forming suffix -ness. This creates an abstract noun describing the quality of decency, modesty, or reasonable behavior.
There's something interesting about how 'decentness' sounds almost formal and old-fashioned, yet it describes something simple—just being not terrible to other people. It's the kind of word your grandparents might use to describe basic human dignity.
