Forms

poenitentiārius m (genitive poenitentiāriī); second declension[1][2] Also spelt paenitentiārius, penitentiārius and penitenciarius.[2][3]

Etymology

It is from Latin paenitentia (“penitence, penance”),[4] and Köbler refers it to paeniteō (“to repent”).[2] Etymonline describes it as an adjective, “of penance”, of which the feminine gave penitentiaria.[4]

Earliest recorded meaning

The earliest record in the DMLBS is from about 1170, a charter of Dryburgh made in the presence of brother James, penitentiary of the pope.[5]

Semantic evolution

In Medieval Latin it named a priest who heard confessions and imposed penances,[6][5] especially one empowered to absolve sins reserved to the pope or the bishop.[3][7] There were papal penitentiaries as well as those of bishops and monasteries;[5][3] a council of Arles in 1260 has bishops send penitentiaries through the villages and towns in Lent to absolve the weak and poor.[7] The DMLBS also has it as an adjective, litterae paenitentiariae, letters about a penance imposed, and as a feminine noun for a woman penitent,[5] and Du Cange cites it for a man on whom penance had been laid.[7]

The Council of Trent made the penitentiary a dignity of cathedral chapters.[7] In Ecclesiastical Latin it is also the president of the Paenitentiaria, the papal tribunal.[1] English penitentiary goes back to the Medieval Latin feminine.[4]
