The quality or state of being disgraceful; shameful or dishonorable nature of something.
From disgraceful + -ness (suffix forming abstract nouns from adjectives). The -ness suffix comes from Old English -nes, creating nouns describing qualities.
English loves stacking suffixes—'disgraceful' (adjective) becomes 'disgracefully' (adverb) becomes 'disgracefulness' (noun of the quality)—showing how one root word can sprout entire families of related parts of speech.
