What are short possessive adjectives?
Short possessive adjectives in Spanish are the unstressed forms that go before a noun to indicate ownership or relationship. They are separate from stressed possessives such as mío, tuyo, suyo, nuestro, and vuestro, which appear after the noun or with the verb ser. The short adjectives are used far more often in everyday speech to say my, your, his, her, our, and their.
List of short possessive adjectives
Here are the most important short possessives and their English equivalents:
yo: mi (singular), mis (plural)
tú: tu (singular), tus (plural)
usted/él/ella: su (singular), sus (plural)
nosotros/nosotras: nuestro/nuestra (singular), nuestros/nuestras (plural)
vosotros/vosotras: vuestro/vuestra (singular), vuestros/vuestras (plural)
ustedes/ellos/ellas: su (singular), sus (plural)
How to match gender and number
The short possessive adjectives agree with the noun they modify in number and, for nosotros and vosotros forms, also in gender. The agreement rules are straightforward:
If the noun is singular, use the singular form: mi, tu, su, nuestro, vuestro.
If the noun is plural, use the plural form: mis, tus, sus, nuestros, vuestros.
For nuestro and vuestro, choose masculine or feminine to match the noun: nuestro libro, nuestra casa, vuestras mochilas.
Examples with family members
Family vocabulary is a frequent reason to use possessives. Notice how the short adjectives change with number and gender of the noun, not the possessor.
Mi madre está en casa.
My mother is at home.
Mis padres viven en Madrid.
My parents live in Madrid.
Tu hermano trabaja mucho.
Your brother works a lot.
Tus hermanos están de viaje.
Your siblings are traveling.
Su abuela prepara la cena.
Their/your (formal) grandmother prepares dinner.
Nuestro tío viene mañana.
Our uncle is coming tomorrow.
Nuestras primas estudian medicina.
Our female cousins study medicine.
Vuestro sobrino tiene cinco años.
Your nephew is five years old.
Possessive adjectives with objects
Short possessive adjectives are equally common with objects. Remember they agree with the object, not with the owner. This is a key difference from English where my/your agree with the speaker or addressee regardless of the noun.
Examples with objects
Mi casa es pequeña.
My house is small.
Mis llaves están en la mesa.
My keys are on the table.
Tu coche es nuevo.
Your car is new.
Tus zapatos están sucios.
Your shoes are dirty.
Su libro está abierto.
His/her/your/their book is open.
Nuestro jardín necesita agua.
Our garden needs water.
Nuestra cocina es grande.
Our kitchen is large.
Vuestros teléfonos suenan.
Your phones are ringing.
Note on ambiguity with su and sus
The forms su and sus can mean his, her, your (formal), their, or your (plural formal). Context is essential to know whose item is referred to. When clarity is needed, Spanish speakers often add a prepositional phrase con or de plus the subject, or use the person’s name or an object like el suyo if using the stressed possessive.
Su casa puede ser suya.
Their/your/his/her house might be theirs/yours.
La casa de María es su casa.
Maria’s house is her house. The de + name construction clarifies ownership.
Common usage patterns and differences from English
There are some important usage patterns to learn so you sound natural in Spanish.
No possessive with body parts in reflexive constructions
Spanish often uses definite articles with body parts instead of possessive adjectives when the possessor is clear from a reflexive verb or context. This is different from English, which uses my, your, etc.
Me lavo las manos.
I wash my hands. Not *me lavo mis manos.
Se rompió el brazo.
He/she broke his/her arm. Not *se rompió su brazo in many reflexive contexts where the reflexive makes the owner obvious.
Possessives vs. de + noun
Both short possessives and the prepositional phrase de + noun express possession. Use short possessives for natural, everyday ownership and de + noun for emphasis or clarity. De + noun literally means of or belonging to.
Mi profesor = my teacher.
El profesor de Juan = Juan’s teacher.
La casa de mi madre = my mother’s house. This avoids ambiguity that might arise with su.
Special considerations: formal you and ustedes
Spanish distinguishes between informal and formal forms of you. The short possessive for usted and ustedes is the same as for él/ella and ellos/ellas: su / sus. This sometimes confuses learners because English uses your for both formal and informal. Remember context or additional phrasing is needed for clarity.
Su hijo está en clase.
His/her/your (formal) child is in class.
Los libros de usted están aquí.
The books of you (formal) are here. Using de + usted clarifies ownership.
Gender-neutral language
Spanish short possessives themselves do not reflect the gender of the possessor, only the noun. This makes them compatible with gender-neutral language practices. When speaking about people with non-binary identities, choose the possessive that matches the possessed noun: mi amigo, mi amiga, mi amigx, depending on the community norms and vocabulary chosen.
Common mistakes and how to avoid them
Beginners often mix up agreement, overuse possessives with body parts, or misuse su/sus. Here are practical tips to avoid these errors.
1. Match the noun, not the owner
Make sure the possessive agrees with the item possessed. For example, say mi casa not *mi casas, and mis libros not *mi libros.
2. Use definite articles for body parts with reflexive verbs
Remember to say me duele la cabeza not *me duele mi cabeza in most reflexive contexts.
3. Clarify with de + name when su is ambiguous
When su could refer to several people, add de + name or use the stressed possessive to remove doubt: la casa de Carlos or la casa de ellos.
4. Choose the right vosotros form in Spain
If you are learning Peninsular Spanish, use vuestro and its forms for the familiar plural you. In Latin America, people typically use su for both singular formal and plural familiar, so context and regional variation matter.
Quick reference: conjugation table (short forms)
To recap the most common short possessives:
Singular: mi, tu, su, nuestro/nuestra, vuestro/vuestra, su.
Plural: mis, tus, sus, nuestros/nuestras, vuestros/vuestras, sus.
Useful sentence patterns
Here are common patterns you will hear and use:
Mi + noun = my + noun
Tu + noun = your (informal) + noun
Su + noun = his/her/your (formal)/their + noun (use context or de + name to clarify)
Nuestro/a + noun = our + noun (match gender)
Vuestro/a + noun = your (plural, Spain) + noun
Practical tips for learners
To internalize short possessives, listen for them in authentic materials like conversations, songs, and shows. Repeat everyday phrases aloud: mi casa, mis libros, tu familia, sus amigos. Practice describing your surroundings in Spanish, focusing on matching the possessive to the noun you name.
Cultural note
Family is central in many Spanish-speaking cultures, so possessive adjectives appear frequently when talking about relatives. Using the correct form shows respect and clarity, especially in formal situations with older people or in professional contexts. In informal family settings, native speakers often use diminutives or kinship terms that pair naturally with short possessives: mi abuelita, tu hermanito, sus primos.
Conclusion
Short possessive adjectives like mi, tu, su, nuestro, and vuestro are essential for talking about family and objects in Spanish. They agree with the noun in number and sometimes gender, differ from English in important ways, and can be clarified with de + noun when ambiguous. With regular exposure and attention to agreement rules, you will use these forms naturally and confidently in everyday conversation.
