The quality or state of being blasé; an attitude of weary indifference or world-weary sophistication.
Formed from blasé plus the English suffix -ness, which creates abstract nouns from adjectives. This pattern is one of the most productive in English word formation.
The -ness suffix is so powerful it can turn almost any adjective into a noun—'blaseness' captures that emotional state as something you can almost hold in your hands!
