In Italian, "voi" is the subject pronoun (in nominative form) of plural "you" in English, equivalent to "vosotros" in Spanish. The conjunctive and disjunctive object pronouns (in accusative and dative forms) in Italian are "vi" and "voi" respectively, corresponding to "os" and "vosotros" in Spanish; while the possessive pronouns are "(il) vostro/(la) vostro//(i) vostri/(le) vostre", corresponding to "vuestro/vuestra//vuestros/vuestras" in Spanish.
On the other hand, the plural form "they" in English is equivalent to "loro" in Italian and "ellos/ellas" in Spanish. If written in capital letter, "Loro" means the formal "you" in plural form in English and "Ustedes" in Spanish.
In Italian, "più" is an adverb that means "more" in English and "más" in Spanish (Please kindly notice that it is the acute accent in "más" and the grave accent in "più").
