Definition of pious

The word "pious" originated from the Latin adjective "pious" (piōsus), which literally means "devout" or "de obligationem" (from the root "PI•-," meaning "pay"). In the context of religion, "pious" refers to a person who is devoted to their faith, follows religious principles, and honors sacred practices. The use of the word "pious" to describe religious devotion became popular in the Middle Ages, when the Catholic Church promoted the concept of "matchless devotion" (devotio (latīna), Deuţiōnā fervōr) as a means of achieving salvation. The root "PI•-" is also cognate with the Latin words "pōnere" (to pay) and "pāter" (father), highlighting the significance of religious obligations and filial devotion in its historical context. In modern usage, "pious" often carries religious or moral connotations and is associated with observance of religious or moral principles that stem from a higher authority or a sense of duty.
