proprio

Forms

proprio (feminine propria, masculine plural propri, feminine plural proprie, adverb propriamente)^[1] Old Tuscan mostly wrote propio, still the popular form.^[2][3][4]

Etymology

It is a learned word, borrowed from Latin proprius (“one's own, peculiar”).^[2][5][6][1] Tuscan reduced it by dissimilation to ⟨propio⟩, the form the 16th-century writers still used;^[2] Migliorini, quoted by DELI, observes that the Latin form won back its place, as it did in Portuguese ⟨proprio⟩, while the popular form survives in Spanish propio.^[2] The same Latin word is French propre and Romanian propriu.^[5][7] The sense “neat, decent” is a calque of the French adjective.^[2]

Most Italian dictionaries derive the Latin adjective from the phrase prō prīvō (“in a private capacity”), read as one word.^[2][5][6][3] De Vaan prefers Forssman's explanation: pro- and an adjective Proto-Italic *prijo- (“own, dear”), from Proto-Indo-European *priH-o-, the source of Sanskrit प्रिय (priyá, “dear, own”) and Gothic 𐍆𐍂𐌴𐌹𐍃 (freis, “free”); the prefix would have come from a verb ⟨*pro-priāre⟩, of which Festus keeps a trace.^[8][1]

Earliest recorded meaning

The first record is in a Tuscan inventory of 1221, the Inventario d'Orlando d'Ugolino, in the sense “belonging to someone, not shared with others”.^[2][6] The noun, in the form propio, “what belongs to someone”, is in Florentine texts of 1264–1284.^[2]

Semantic evolution

The adverb, “precisely, exactly”, is in Dante's Convivio (1304–1308).^[2] As a grammatical term, nome proprio “proper noun” is in Leon Battista Alberti about 1438, and proprio of a word that says exactly what is meant is in Benedetto Varchi before 1565.^[2] The sense “seemly, decent”, recorded in 1831, follows the French adjective, like proprietà “neatness”, found from 1666.^[2] The Old Italian noun could also mean property: Giovanni Villani discusses the dispute whether Christ “non ebbe propio” (owned nothing).^[9]

Grammars now use proprio as a possessive referring back to the subject, obligatory in impersonal sentences, and as the adverb “really, just”.^[6][3][10]
