nostri

Nostri is the masculine plural form of the Italian possessive adjective nostro, meaning “our.” It is used to indicate possession with masculine plural nouns, for example: i nostri amici (our friends), i nostri libri (our books).

Forms of the related possessive adjective in Italian include: nostro (masculine singular), nostra (feminine singular), nostri (masculine plural), and nostre (feminine plural). Possessive adjectives in Italian typically agree with the noun they modify in gender and number, and are usually preceded by a definite article: il nostro libro, la nostra casa, i nostri amici, le nostre idee.

Usage notes: Nostri functions as a standard possessive determiner in noun phrases, marking ownership from the first-person plural perspective. It is commonly used in everyday Italian, in both spoken and written language, to express belonging to the group including the speaker (e.g., “Questi sono i nostri progetti” – “These are our projects”).

Etymology: Nostri derives from Latin something akin to “noster,” historically used to express “our” or “of us,” and has evolved into the modern Italian forms nostro, nostra, nostri, nostre.
