The quality of showing proper respect, duty, and affection toward one's parents; the state of being a devoted child.
From 'filial' (Latin 'filialis', from 'filius' meaning 'son') + '-ness' (Old English suffix forming abstract nouns). Describes the essential quality of filial devotion.
While 'filial duty' gets thrown around, 'filialness' as a noun is pretty rare—it's a word for philosophers and poets to discuss the essence of what it means to be a good child to parents!
