Possessive Adjectives

Possessive adjectives are used to modify nouns to show to whom a noun belongs. In Spanish, the possessive adjective will agree in number and gender with the noun it modifies, not with the owner.

Note that the forms are the same for third person singular and plural. If it is not c clear from the context of the sentence who the owner is, then you can use “de” plus the pronoun to make it clear.

For example:   el libro de Antonio instead of su libro

Here are the singular forms:

	singular	plural
first person	mi	nuestro/a
second person	tu	vuestro/a
third person	su	su

mi libro tu libro su libro nuestro libro nuestra casa su libro

my book your (familiar) book his book; her book; your (formal) book our book our house their book

Here are the plural forms:

	singular	plural
first person	mis	nuestros/as
second person	tus	vuestros/as
third person	sus	sus

mis libros tus libros sus libros nuestros libros nuestras casas sus libros

my books your (familiar) books his books; her books; your (formal) books our books our houses their books
