Introduction to Spanish Possessive Adjectives

Possessive adjectives show ownership and relationships – they tell us who something belongs to. While English has simple forms like “my” and “your,” Spanish possessive adjectives change based on what’s being owned, not who owns it. The patterns are consistent and you’ll master them quickly!

Short Form Possessive Adjectives

Examples:

  • “las casas mías” (the houses of mine)
  • “un amigo suyo” (a friend of his/hers/yours)

When to Use Short Form vs Long Form

Use Short Form (Before Noun) for:

  • Simple possession without emphasis
  • Everyday conversations
  • Most common usage

Examples:

  • Mi coche es rojo.” (My car is red.)
  • Nuestra casa es grande.” (Our house is big.)

Use Long Form (After Noun) for:

  • Emphasis or clarification
  • When the noun is omitted but understood
  • After the verb “ser”

Examples:

  • “El coche es mío.” (The car is mine.)
  • “Estos libros son tuyos.” (These books are yours.)

Agreement Rules

Key Points:

  1. Short forms (mi, tu, su): Only change for number (mi/mis)
  2. Long forms (mío, tuyo, suyo): Change for both gender and number
  3. Nuestro/vuestro: Always change for gender and number

Agreement Examples:

  • mi amigo” (my friend – masculine singular)
  • mis amigos” (my friends – masculine plural)
  • mi amiga” (my friend – feminine singular)
  • mis amigas” (my friends – feminine plural)
  • “el libro mío” (the book mine – masculine singular)
  • “los libros míos” (the books mine – masculine plural)
  • “la casa mía” (the house mine – feminine singular)
  • “las casas mías” (the houses mine – feminine plural)

Common Usage Scenarios

Family Members:

  • mi madre” (my mother)
  • tu padre” (your father)
  • nuestros hijos” (our children)
  • sus abuelos” (his/her/their grandparents)

Objects and Possessions:

  • mi teléfono” (my phone)
  • tu coche” (your car)
  • nuestra casa” (our house)
  • sus libros” (his/her/their books)

Relationships:

  • mi amigo” (my friend)
  • tu profesor” (your teacher)
  • nuestros vecinos” (our neighbors)

Special Cases and Clarification

When “su/sus” is Ambiguous:

Since “su/sus” can mean his, her, your (formal), or their, you can clarify with:

  • el libro de él” (his book)
  • la casa de ella” (her house)
  • los zapatos de usted” (your shoes – formal)
  • las llaves de ellos” (their keys)

With the Verb “Ser”:

Long forms are used after “ser” even when the noun is mentioned first:

  • “Este coche es mío.” (This car is mine.)
  • “Esas ideas son suyas.” (Those ideas are his/hers.)

Common Mistakes to Avoid

  1. Don’t forget number agreement – mi libro vs mis libros
  2. Don’t mix up short and long forms – mi casa vs casa mía
  3. Don’t ignore gender with nuestro/vuestro – nuestro libro vs nuestra casa
  4. Don’t use English word order – mi casa not casa mi

Frequently Asked Questions About Spanish Possessive Adjectives

Possessive adjectives show ownership or relationship. In English: my, your, his, her, our, their. In Spanish: mi, tu, su, nuestro, vuestro, su. Example: “mi casa” (my house), “nuestro carro” (our car).

Here is the complete list: mi (my), tu (your – informal), su (his/her/its/your formal/their), nuestro/a (our), vuestro/a (your plural – Spain), su (their/your plural). Example: mi libro, tu hermana, su casa, nuestro perro, vuestro pueblo, sus amigos.

Only nuestro and vuestro change gender. All others (mi, tu, su) do NOT change. Examples: nuestro perro (our dog – masculine), nuestra casa (our house – feminine). Mi, tu, su stay the same: mi perro, mi casa, tu perro, tu casa, su perro, su casa.

Yes. All possessive adjectives have plural forms. Add -s to mi, tu, su: mis, tus, sus. For nuestro/vuestro, add -s to the end: nuestros, vuestros (masculine) or nuestras, vuestras (feminine). Examples: mi amigo (my friend) → mis amigos (my friends), nuestra casa → nuestras casas.

“Mi” is a possessive adjective that goes BEFORE the noun: “mi libro” (my book). “Mío” is a possessive pronoun that replaces the noun and usually goes AFTER the verb “ser”: “El libro es mío” (The book is mine). You cannot say “el libro es mi”. Use “mío” for “mine”.

For informal “you” (tú), use “tu”: “tu casa” (your house). For formal “you” (usted), use “su”: “su casa” (your house – formal). The same word “su” is also used for “his”, “her”, “its”, and “their”. Context tells you who it refers to.

“Our” is “nuestro” for masculine nouns and “nuestra” for feminine nouns. Plural forms: “nuestros” (masculine plural), “nuestras” (feminine plural). Examples: nuestro perro (our dog), nuestra casa (our house), nuestros amigos (our friends), nuestras flores (our flowers).

In Spanish, you usually use the definite article (el, la, los, las) instead of the possessive adjective for body parts and clothing when the owner is already clear. Example: “Me duele la cabeza” (My head hurts – literally “The head hurts me”) NOT “Me duele mi cabeza”. “Lávate las manos” (Wash your hands) NOT “Lávate tus manos”.

“Su” is singular (one object owned): “su libro” (his/her/their/your formal book). “Sus” is plural (multiple objects owned): “sus libros” (his/her/their/your formal books). Both “su” and “sus” can mean his, her, its, their, or your (formal/plural).

Possessive adjectives go BEFORE the noun. Word order: possessive adjective + noun. Examples: “mi casa” (my house), “tu perro” (your dog), “nuestro profesor” (our teacher). They cannot go after the noun (except in poetry or very formal old Spanish).

“My” is “mi” for singular nouns and “mis” for plural nouns. Examples: mi hermano (my brother), mi hermana (my sister), mis hermanos (my brothers), mis hermanas (my sisters). “Mi” does NOT change gender – it is the same for masculine and feminine nouns.

Common mistakes: 1) Changing “mi/tu/su” for gender (they don’t change), 2) Forgetting to make “nuestro/vuestro” feminine, 3) Using possessive adjectives with body parts when you need the article, 4) Confusing “mi” (my) with “mí” (me – with accent), 5) Forgetting plural forms “mis/tus/sus”, 6) Using “su” when you mean “tu” for informal “your”.

“Their” is “su” for singular objects and “sus” for plural objects. Examples: su casa (their house), sus casas (their houses). Because “su/sus” can mean his, her, its, their, or your (formal), you can add “de ellos” (of them) for clarity: “la casa de ellos” (their house).

Yes! “Vuestro/a/os/as” is used only in Spain for the informal plural “you” (vosotros). “Su” is used for formal “you” (usted/ustedes) in all Spanish-speaking countries. In Latin America, “su” is used for both formal and informal plural “you” because they don’t use “vosotros”.
