altra

Altra can refer to more than one thing, depending on context. In Italian, uusia word "altra" is the feminine singular form of the adjective "altro," meaning "other" or "another." It agrees with feminine singular nouns and is used as both a determiner and, in some cases, a pronoun. Examples include un’altra opzione (another option) and l’altra persona (the other person). The masculine forms are "altro" (singular), "altri" (plural), and the feminine plural is "altre." The term derives from Latin alter, via the evolution of Italian vocabulary.

In Italian grammar, "altra" helps distinguish things that are different from what has already been mentioned or assumed. It appears in everyday speech and writing to indicate an alternative or additional item, and it is commonly preceded by an article or numeral, as in "un’altra volta" or "l’altra metà." Its usage is governed by standard gender and number agreement rules that apply to most adjectives in Italian.
