Spanish Possessive Adjectives: Mi, Tu, Su, Nuestro, and More

Spanish possessive adjectives identify an owner and appear before the possessed noun. Mi, tu, and su change only for number, while nuestro and vuestro also match the noun's gender.

Use Spanish possessive adjectives before nouns

Place the possessive directly before the noun without an article: mi casa, tu libro, and sus amigos.

Mi hermana vive aquí.
My sister lives here.Mi stays singular because hermana is one possessed person.

Quick check

Choose “my house.”

Match mi, tu, and su to the noun's number

Use mi, tu, or su with one possessed thing and mis, tus, or sus with multiple things.

Estos son tus libros.
These are your books.Tus is plural because libros is plural.

Make nuestro and vuestro fully agree

Nuestro and vuestro change for the possessed noun's gender and number: nuestro coche, nuestra casa, nuestros libros, and nuestras llaves.

Nuestra casa es pequeña.
Our house is small.Nuestra matches the feminine singular noun casa.
