Possessive Pronouns in Spanish.Pronombres posesivos.

Possessive pronouns replace a noun phrase and indicate ownership or association. Spanish possessive pronouns agree in gender and number with the noun they replace, not with the possessor.

The forms are:

• Mine: mío, mía, míos, mías
• Yours, informal singular: tuyo, tuya, tuyos, tuyas
• His, hers, yours (formal singular), or theirs: suyo, suya, suyos, suyas
• Ours: nuestro, nuestra, nuestros, nuestras
• Yours, informal plural in Spain: vuestro, vuestra, vuestros, vuestras

Possessive pronouns can avoid repeating a noun:

Es mi libro. Es mío. — It is my book. It is mine.

Possessive pronouns take a form that matches the gender and number of the noun they replace. The complete set is:

When a possessive pronoun stands alone, it commonly appears with a definite article:

• El libro es mío. — The book is mine.
• La casa es mía. — The house is mine.
• Los libros son míos. — The books are mine.
• Las casas son mías. — The houses are mine.

Possessive pronouns indicate ownership or an association with someone. They replace a noun or noun phrase when the referent is understood from context.

Indicating ownership

• Este libro es mío. — This book is mine.
• La casa grande es nuestra. — The big house is ours.

Replacing a noun already mentioned

• Tus zapatos son más cómodos que los míos. — Your shoes are more comfortable than mine.
• Mis amigos son divertidos. ¿Cómo son los tuyos? — My friends are fun. What are yours like?

Showing relationships or association

• El coche es suyo. — The car is his, hers, yours, or theirs.
• Estos problemas son nuestros. — These problems are ours.

Responding to questions

• ¿De quién es esta mochila? Es mía. — Whose backpack is this? It is mine.
• ¿Son tus llaves? No, son suyas. — Are these your keys? No, they are his, hers, yours, or theirs.

Because suyo and its forms can refer to several people, context or an added phrase such as de él or de ellos may be needed for clarity.

Possessive pronouns agree with the noun they replace in both number and, where applicable, gender.

Number agreement

The pronouns mío, tuyo, suyo and their forms change from singular to plural according to the noun:

• El libro es mío. — The book is mine.
• Los libros son míos. — The books are mine.
• La casa es tuya. — The house is yours.
• Las casas son tuyas. — The houses are yours.

Gender agreement

The forms of mío, tuyo and suyo, as well as the forms beginning with nuestro and vuestro, also change according to the noun's gender:

• El coche es nuestro. — The car is ours.
• La casa es nuestra. — The house is ours.
• El libro es vuestro. — The book is yours (informal plural, in Spain).
• Las mesas son vuestras. — The tables are yours (informal plural, in Spain).

The unstressed forms mi, tu and su are possessive adjectives, not pronouns; they agree in number but do not change for gender: mi casa and mi libro, but mis casas and mis libros.

Spanish distinguishes between unstressed possessive adjectives, which accompany a noun, and stressed possessive forms, which can function as pronouns or follow a noun.

Unstressed forms

Unstressed forms come before the noun. They are possessive adjectives, not independent pronouns. Mi, tu and su have one form for both genders and change only for number. Nuestro and vuestro agree in gender and number.

• mi casa — my house
• tus libros — your books
• nuestras sillas — our chairs

Stressed forms

Stressed forms are mío, tuyo, suyo, nuestro and vuestro, with their feminine and plural forms. They can stand alone, usually with a definite article, or follow a noun for emphasis or contrast.

• El libro es mío. — The book is mine.
• La casa tuya es más grande. — Your house is bigger.
• Los libros suyos están aquí. — His, hers, yours, or their books are here.
• Esa es la mochila tuya, no la mía. — That is your backpack, not mine.

Stressed forms often make a contrast or ownership especially clear. The phrase la casa tuya is grammatical, but tu casa is the usual neutral form.

When a possessive form replaces a noun phrase and stands alone, it generally follows a definite article. Both the article and the possessive pronoun agree with the omitted noun in gender and number.

• El mío — mine (masculine singular)
• La tuya — yours (informal singular, feminine singular)
• Los suyos — his, hers, yours, or theirs (masculine plural)
• Las nuestras — ours (feminine plural)

1. Place the definite article before the stressed possessive pronoun when it replaces a noun phrase: el mío, la tuya, los nuestros, las suyas.
2. Match the article and pronoun to the gender and number of the omitted noun.
3. Do not use an article before an unstressed possessive adjective that directly precedes a noun: mi libro, not el mi libro in standard Spanish.

After the verb ser, the stressed possessive usually appears without an article:

• El libro es mío. — The book is mine.
• Las llaves son suyas. — The keys are his, hers, yours, or theirs.
• La casa es nuestra. — The house is ours.
• Los problemas son vuestros. — The problems are yours (informal plural, in Spain).

Using possessive forms correctly requires attention to agreement, articles, and the difference between adjectives and pronouns.

• Incorrect agreement: The pronoun must match the omitted noun. El mío no puede sustituir a la casa; la forma correcta es la mía. — El mío cannot replace la casa; the correct form is la mía.
• Adding an article in the wrong construction: Use an article when the stressed form stands alone as a noun phrase: Quiero el mío. — I want mine. After ser, no article is normally used: El libro es mío. — The book is mine.
• Confusing adjectives and pronouns: An unstressed possessive accompanies a noun, whereas a stressed form replaces it: Es mi libro. Es mío. — It is my book. It is mine.
• Using a form that does not match the noun: Las casas son mías, not Las casas son mío. — The houses are mine, not Las casas son mío.
• Leaving suyo ambiguous: Since suyo can mean his, hers, yours, or theirs, clarify when necessary: El coche es suyo, el de Ana. — The car is hers, Ana's.

Check the omitted noun's gender and number, choose an adjective or pronoun according to the construction, and add an article when a standalone stressed form requires one.

Spanish possessive forms reflect the person being addressed, not a separate formal or informal set of stressed pronouns. The main contrast is between tu and tuyo for informal singular tú, and su and suyo for formal singular usted. Su and suyo can also refer to third persons.

For formal address, use su before a noun and suyo after a noun or as a pronoun:

• ¿Es su casa, señor? — Is it your house, sir?
• ¿La casa es suya? — Is the house yours?

For informal singular address, use tu and tuyo:

• ¿Es tu casa? — Is it your house?
• ¿La casa es tuya? — Is the house yours?

In most of Latin America, ustedes is used for both plural formal and informal address, so su and suyo serve both contexts. In Spain, vosotros normally takes vuestro, while formal plural ustedes takes su.

Use the chart to review the stressed possessive forms. The forms agree with the noun that is replaced.

To practice, substitute a noun phrase with the matching possessive pronoun:

• Este libro es de María. Este libro es suyo. — This book belongs to María. This book is hers.
• Estas casas son de nosotros. Estas casas son nuestras. — These houses belong to us. These houses are ours.

Flashcards, substitution exercises, short written sentences, and conversations with native speakers can help you review the forms. Pay attention to possessive pronouns in Spanish books, films, podcasts, and everyday conversation.
