What does su mean?
su is a possessive adjective that can mean your (formal), his, her, its, their, or your (plural formal in some regions). It is used before a noun to show possession or relationship. Because su can have multiple meanings, context is important to understand who owns or is related to the thing mentioned.
Basic examples showing meaning
su casa — the house that belongs to him, her, you (formal), or them
su teléfono — his phone, her phone, your phone (formal), or their phone
su nombre — his name, her name, your name (formal), or their name
Using su in polite conversation
One of the most common uses of su is to show respect by addressing someone formally. Use su instead of the informal possessive when speaking with elders, strangers in formal settings, or service staff when you prefer politeness.
Polite examples
Buenos días, ¿cómo está su familia? — Good morning, how is your family? (formal)
¿Puedo llamar a su oficina? — Can I call your office? (formal)
Gracias por su ayuda. — Thank you for your help. (formal)
Using su for third-person possession
su is also used to talk about something that belongs to another person or people. To clarify who owns the object, speakers often add an optional phrase with a person’s name or a noun with de + name.
Third-person examples
El coche es su coche. — It is his/her/their car. (ambiguous)
El coche es el coche de María. = El coche es su coche de María. — The car belongs to María. (clarified)
Voy a devolver su libro a Juan. — I am going to return his book to Juan.
Using su with plural owners
When the owner is plural, su still stays the same. Context or extra words clarify whether the owner is a group. To avoid ambiguity, you can use de ellos or de ellas to explicitly say their.
Plural examples
¿Dónde están sus llaves? — Where are their keys? (could be yours (formal) or theirs)
Las llaves son su casa de los vecinos. — The keys are from the neighbors house.
Clarify: Las llaves son de ellos. — The keys are theirs.

Understanding possible confusion and how to clarify
Because su can mean many things, beginners should learn easy strategies to remove ambiguity: add de + noun or use a proper name, or use plural clarifiers like de ellos or de ellas.
Clarifying techniques
Use de + name: su casa de Carlos — Carlos’s house (better: la casa de Carlos)
Use de + pronoun: su libro de ella — her book (better: el libro de ella)
Use plural clarifier: su problema de ellos — their problem (better: el problema de ellos)
Common mistakes beginners make
Beginners often confuse su with informal possessives like tu or plural sus, or forget to match number and clarity. Here are typical errors with corrections.
Mistake and correction examples
Mistake: ¿Dónde está su amigo? when speaking informally to a friend
Correction: ¿Dónde está tu amigo? — Use tu for informal you.
Mistake: El padre perdió su trabajo. (ambiguous if you mean the child’s father or someone else)
Correction: El padre de María perdió su trabajo. — Specify with de + name or use a name.
Mistake: Usar su para posesión plural y no aclarar
Correction: Sus zapatos (plural) vs su zapato (singular): match the noun number and add clarifier if needed.
Vocabulary list: key words to pair with su
su teléfono — phone
su casa — house
su nombre — name
su correo electrónico — email

Practical tips for remembering su
