Vuestra

Vuestra is a Spanish possessive determiner used to indicate possession by the group addressed as vosotros. It is the feminine singular form and must agree with the noun it modifies. The corresponding forms are vuestro (masculine singular), vuestros (masculine plural), and vuestras (feminine plural).

Usage and examples: before a feminine singular noun, as in vuestra casa (your house) or vuestra idea (your idea). For masculine nouns, the forms are in the masculine column, for example vuestro coche (your car). When referring to multiple feminine nouns, you would use vuestras casas (your houses). In many dialects, especially in Spain, vosotros and its possessives are standard; in Latin American Spanish, ustedes is used instead of vosotros, and the common possessive with ustedes is usually su/sus rather than vuestra/vuestras, though regional variation can occur.

Pronoun use: vosotros can also appear as a possessive pronoun, as in la vuestra, los vuestros, depending on formality and clarity. This form tends to be less common in everyday speech and can be replaced by phrases like la casa de ustedes (the house of you all) in regions where ustedes is standard.

Origins and notes: vuestra derives from the Latin possessive form similar to vos‑, historically linked to vester/vestro forms. It remains the feminine singular of the second-person plural possessive in modern Spanish.
