nessuna

Nessuna is the feminine singular form of the Italian negative determiner and pronoun nessuno. It expresses the idea of "no" or "none" in relation to a feminine noun, and can function as a determiner before the noun (for example, nessuna idea, nessuna traccia) or as a pronoun replacing a feminine noun (for example, non c'è nessuna). It is used in negative sentences to indicate the absence of any item or person that would otherwise be present.

In Italian, nessuna agrees in gender and number with the noun it accompanies. The masculine counterparts are nessuno and nessun; nessuna corresponds to feminine singular nouns, while nessuno can function as both a masculine singular determiner/pronoun and, in some contexts, a figure of speech or pronoun. A common construction is "Non c'è nessuna + [feminine noun]" or the shorter form "Nessuna + [feminine noun]" when the noun is understood from context. Examples include "Non c'è nessuna possibilità" and "Nessuna delle due ha vinto." Nessuna is also used in questions and negative replies to emphasize the absence of any option or respondent.

Etymologically, nessuna comes from the negation ne- combined with uno, meaning "not one" or "none." It shares its conceptual origin with nessuno, the masculine form. In standard Italian, nessuna is a routine choice whenever the referent is feminine and singular, while other forms such as nessun and nessuno handle masculine forms or other syntactic roles.
