The quality or state of lacking devoutness; absence of religious sincerity or dedication.
From 'devoutless' (adjective) plus '-ness' suffix. Stacks three morphemes: devout + -less + -ness, creating an abstract noun describing the absence of a quality.
Words like 'devoutlessness' show how English can theoretically create nearly infinite words by stacking suffixes—but they rarely survive because they sound clunky and we prefer simpler alternatives like 'irreverence' or 'insincerity'.
