The quality of being dutiful; a careful and conscientious performance of one's duties and responsibilities.
From dutiful + -ness (noun suffix creating abstract nouns). Dutiful combines duty + -ful; both suffixes trace through Old English and Old French roots.
Ancient cultures valued dutifulness so highly that they made it a core virtue—Confucianism, for instance, built entire ethical systems around dutiful behavior to family and state!
