The state or quality of being blessed; supreme happiness or a sense of divine favor and well-being.
From 'blessed' plus the noun-forming suffix '-ness,' which converts adjectives to abstract nouns. Rooted in Old English 'bletsian' (to consecrate or praise).
The Beatitudes in Christian scripture are sometimes called 'Blessednesses'—it's one of the few English words that captures both spiritual grace and deep happiness as a single concept.
