Forms

proprietario m (plural proprietari, feminine proprietaria)[1] The popular form propietario is old and is still used in popular speech.[2][3][4][5]

Etymology

It is borrowed from Late Latin proprietārius (“owner”), a learned word formed from Latin proprietās (“property, ownership”) with the suffix -ārius.[6][2][7][8][1] In Roman law the word named the owner of a thing as opposed to one who held only its use and fruits.[9][5]

The dictionaries disagree on the date: DELI gives the 14th century, from the “Trattato dei peccati”, and GRADIT and Devoto–Oli the end of the 14th century, while Nocentini dates it to the end of the 15th.[10][6][2][7] DELI notes that the example from Jacopone da Todi quoted by the Crusca and by Tommaseo comes from apocryphal lauds printed at Venice in 1617.[10]

Earliest recorded meaning

In the Trattato dei peccati the word is used of members of religious orders who own property although they have vowed to live without anything of their own: Quelli di religione che son propietari ed hanno botato di vivere sanza proprio.[4][5] This disapproving use, against the vow of poverty, recurs in Giovanni Dominici and in Bandello.[4]

Semantic evolution

Beside its religious use the word soon had the general sense “one who owns something”, and Tommaseo records legittimo proprietario and the contrast between the owner and the usufructuary.[4][5] Used absolutely it named a person living on property, as opposed to one who lives by his work or a salary.[5] In the 18th century a proprietario was also an officer given command of a regiment as an honour, without the duty of serving with it.[8][11]

As an adjective the word means “relating to property” (diritti proprietari).[8][2] In computing it describes a product offered as a standard of its own by the company that makes it and holds its rights, a sense that the GDLI added in its 2009 supplement.[6][2][4]
