Possessive Adjectives are used to show to whom

Possessive Adjectives are used to show to whom something belongs. In English, the Possessive Adjectives are: my, your, his, her, its, our, their. EX: my book, your book, his book, her book, our book, their book, etc.

In Spanish the Possessive Adjectives are: my book mi libro our book **nuestro libro our house nuestra casa your [tú] book tu libro your book **vuestro libro his book su libro your house vuestra casa her book su libro their book su libro its book su libro your [Uds]] book su libro your [Ud] book su libro

Since these are adjectives, they must agree with the noun in number [singular / plural]. If the noun is singular [book], use the singular form of the Poss. Adj. as shown above.

If the noun is plural [books], you must use the plural form of the Possessive Adjective. The plural forms are made like any other word in Spanish. Since all the Possessive Adjectives end in a vowel, simply add “s” to make it plural:

my books mis libros our books nuestros libros our houses nuestras casas your books tus libros your books vuestros libros his books sus libros your houses vuestras casas q her books sus libros their books sus libros its books sus libros your [Uds] books sus your [Ud] books sus libros
