The quality of being august; dignity, majesty, or impressive solemnity.
From 'august' + '-ness' (the noun-forming suffix that creates abstract nouns). Follows patterns like 'kindness' or 'brightness'.
There's something almost poetic about creating a noun meaning 'the quality of majesty'—it's how you'd describe the feeling when you stand in a cathedral or see a mountain sunrise, but can't quite find the words.
