What Are Possessive Adjectives in Spanish?
Possessive adjectives indicate who owns or is associated with a noun. Unlike English—where words like “my,” “your,” or “their” never change shape—Spanish possessive adjectives must agree in number (singular or plural) and sometimes gender (masculine or feminine) with the noun being possessed, not the person who owns it.
In the context of talking about family, this means the word you choose depends directly on whether you are talking about one relative or several.
Owner —> [ Possessive Adjective ] —> Possessed Noun (Determines Gender & Number)
Short-Form Possessive Adjectives (Unstressed)
Short-form possessives are the most common type. They always appear before the noun they modify.
Singular vs. Plural Agreement Rules
When describing family members, match the short-form adjective to the number of relatives:
| Person | English | Singular Noun | Plural Noun |
| Yo (I) | my | mi padre | mis padres |
| Tú (You – informal) | your | tu hermano | tus hermanos |
| Él / Ella / Usted | his / her / your (formal) | su tía | sus tías |
| Nosotros / Nosotras | our | nuestro / nuestra abuelo(a) | nuestros / nuestras abuelos(as) |
| Vosotros / Vosotras | your (plural informal) | vuestro / vuestra primo(a) | vuestros / vuestras primos(as) |
| Ellos / Ellas / Ustedes | their / your (plural) | su familia | sus familias |
Understanding the Ambiguity of “Su” and “Sus”
The adjective su (and its plural sus) can mean his, her, its, your (formal), or their. To avoid confusion in family conversations, Spanish speakers often clarify the relationship using a prepositional phrase: [Artículo] + [Familia] + de + [Persona].
Ambiguous: Su casa es grande. (His/Her/Their house is big.)
Clear: La casa de ella es grande. (Her house is big.)
Clear: Los primos de Fernando son amables. (Fernando’s cousins are kind.)

Frequently Asked Questions
What is the main difference between "mi" and "mío"?
Mi is an unstressed possessive adjective placed before the noun (mi padre = my father). Mío is a stressed possessive adjective placed after the noun (un amigo mío = a friend of mine) or used as a pronoun with an article (el mío = mine).
Do possessive adjectives in Spanish agree with the owner or the object?
In Spanish, possessive adjectives always agree in number and gender with the noun being possessed (the object or person), not with the person who owns it.
Why do "nuestro" and "vuestro" change ending while "mi" and "tu" do not?
Mi, tu, and su only change for number (mi/mis, tu/tus, su/sus). However, nuestro and vuestro end in -o, which means they change for both gender and number (nuestro, nuestra, nuestros, nuestras).
How do I avoid confusion when using "su" or "sus"?
Because su can mean his, her, its, your, or their, you can replace it with the structure el/la/los/las + [noun] + de + [pronoun/person]. For example, use los padres de él instead of sus padres.
What does "mi jefa" mean in Mexican Spanish?
In Mexican Spanish, mi jefa (or mi jefe for male) literally translates to “my boss,” but it is widely used as a warm, informal term for “my mom.”
