Forms

nostro (feminine nostra, masculine plural nostri, feminine plural nostre)[1] Old Italian also had the form nosso, used in Albertano's translation and common across Italy.[2][3]

Etymology

It is inherited from Latin noster (“our”), from Latin nōs (“we”), with the suffix -ter that marks a contrast between two, as in alter (Italian altro).[4][5][6][7] The word is panromance: French notre, Occitan nostre, Catalan nostre, Spanish nuestro, Portuguese nosso, Sardinian nostru, Friulian nestri, Dalmatian nuester and Romanian nostru.[5][8]

De Vaan reconstructs Proto-Italic *nosteros and, with a question mark, a PIE possessive Proto-Indo-European *n̥s-tero-.[9][1] Devoto finds a similar formation only in Greek ἡμέτερος (hēméteros), while German unser has a simpler derivative.[7] The Latin genitive nostrum “of us” was originally the genitive plural of the possessive.[9]

Earliest recorded meaning

DELI's first record is in the Ritmo cassinese, at the end of the 12th century, as the adjective “belonging to us”;[4] GRADIT dates the word to the second half of the 12th century.[6] The plural i nostri, “our family, our relatives, our side”, appears in the Ritmo bellunese of 1193–1196.[4]

Semantic evolution

Old Italian already used Nostro Signore for Christ, as in Dante's “Quanto tesoro volle Nostro Segnore / in prima da san Pietro” (how much treasure our Lord asked of Saint Peter, Inferno 19), and Nostra Donna for the Virgin.[10][11] The plural i nostri named one's own people or party, as in Petrarch.[10]

Two adjectives meaning “of our country, local” grew from it: nostrano, recorded in the Statute of the Gabella of Siena (1301–1303), and nostrale, in the translation of Crescenzi of about 1350.[4] DEI finds Medieval Latin nostranus at Arezzo as early as 994.[3] The naval nostromo, the boatswain, comes from older nostr'homo, “our man”.[2]

Modern uses include the plural of majesty or modesty (a nostro avviso), il nostro for an author already under discussion, and the exclamation arrivano i nostri!, from the rescue scenes of old adventure films.[11][1] GRADIT lists Cosa Nostra and Padre nostro among its phrases.[6]
