Spanish Possessive Pronouns Overview

Spanish possessive pronouns show ownership or relationships between people and things. They answer the question "whose?" and must agree with the noun they modify, not the owner. Key Rule: Possessive pronouns agree with the thing possessed, not the person who owns it. Two Types: - Short forms: mi, tu, su (go before noun) - Long forms: mío, tuyo, suyo (go after noun or stand alone) Most commonly, you'll use the short forms that go before the noun.

Examples

mi casa
my house (short form before noun)
la casa es mía
the house is mine (long form after verb)
nuestros libros
our books (agrees with "libros", not "we")

Short Form Possessive Pronouns

Short form possessives go before the noun and are the most commonly used:

Agreement Rules for Short Forms

Short form possessives agree in number with the noun they modify: mi/tu/su: Only change for plural (mis/tus/sus) nuestro/vuestro: Change for both gender and number Important: They agree with the thing possessed, not the owner.
mi casa mis casas
my house → my houses (number agreement)
nuestro coche nuestra casa
our car → our house (gender agreement)
nuestros libros nuestras revistas
our books → our magazines (gender + number)
vuestro profesor vuestra profesora
your teacher (m) → your teacher (f) (Spain)

The Ambiguous "Su/Sus"

Su and sus can mean his, her, its, your (formal), their, or your (plural). This can cause confusion:

Multiple Meanings of Su/Sus

The same form "su" can refer to different owners:
su casa
his house / her house / your house (formal) / their house
sus libros
his books / her books / your books (formal) / their books

Clarifying Su/Sus

To avoid confusion, you can use de + pronoun or de + noun:
su casa la casa de él
his house → the house of him (his house)
su casa la casa de ella
her house → the house of her (her house)
su casa la casa de usted
your house → the house of you (your house, formal)
su casa la casa de María
her house → María's house

Long Form Possessive Pronouns

Long form possessives can stand alone or go after the noun. They agree in both gender and number:

Common Possessive Mistakes

Here are common mistakes Spanish learners make with possessive pronouns: Mistake 1: Making possessives agree with the owner instead of the thing possessed Mistake 2: Using long forms when short forms are needed Mistake 3: Forgetting gender agreement with nuestro/vuestro Mistake 4: Overusing su without clarification Learning to avoid these mistakes will make your Spanish sound natural.

Examples

María tiene su casa (thinking "her" = feminine) María tiene su casa
Wrong thinking → Right: María has her house (su agrees with casa, not María)
mi casa es mía mi casa / la casa es mía
Wrong: my house is mine → Right: my house / the house is mine
nuestro casa nuestra casa
Wrong: our house → Right: our house (feminine agreement)
su casa (ambiguous) la casa de él/ella
Unclear: his/her house → Clear: his house / her house
