How to use this page

Use this page to understand relative clauses as part of Spanish sentence structure. First learn the basic pattern. Then compare restrictive and non-restrictive clauses, study the main relative pronouns, and finally practise prepositions and subjunctive contrasts.

Basic pattern

The relative clause usually follows the noun it describes.

el hombre que vive aquí
the man who lives here

Most common connector

Que is the most frequent Spanish relative pronoun.

la película que vimos
the film that we watched

Commas matter

Commas show whether the clause identifies or only adds information.

Mi hermana, que vive en Lima, viene hoy.

What is a relative clause in Spanish?

A relative clause is a dependent clause that gives more information about a noun, pronoun or whole idea. The word it refers to is called the antecedent. In Spanish, the relative clause normally comes immediately after the antecedent.

Spanish sentence Antecedent Relative clause English meaning
El libro que compré es interesante. el libro que compré The book that I bought is interesting.
La mujer que vive aquí es médica. la mujer que vive aquí The woman who lives here is a doctor.
La ciudad donde nací es pequeña. la ciudad donde nací The city where I was born is small.
Eso es lo que quiero. lo / idea que quiero That is what I want.
Memory line: relative clauses in Spanish usually stand right after the word or idea they describe.

Basic Spanish relative clause pattern

The standard pattern is: noun or idea + relative pronoun + relative clause. The relative clause cannot usually stand alone because it depends on the antecedent.

Pattern part Spanish example Function
Antecedent la casa The noun being described.
Relative pronoun que Connects the noun to the clause.
Relative clause compramos Gives more information about the noun.
Complete phrase la casa que compramos The house that we bought.

La casa que compramos está cerca del centro.
The house that we bought is near the city centre.

Que: the most common Spanish relative pronoun

Que is the most common relative pronoun in Spanish. It can refer to people, things, animals and ideas. In English it can often mean “that”, “which”, “who” or “whom”, depending on the sentence.

Spanish example Que refers to English meaning Structure
El libro que leí es bueno. A thing The book that I read is good. noun + que + clause
La persona que llamó es mi jefe. A person The person who called is my boss. noun + que + verb
El perro que vimos era enorme. An animal The dog that we saw was huge. noun + que + clause
Lo que dices es importante. An idea What you say is important. lo que + clause

Quien and quienes: relative clauses about people

Quien and quienes refer to people. They are especially common after prepositions and in non-restrictive clauses. In many simple restrictive clauses, que is more common.

Spanish example Relative pronoun English meaning Note
Mi profesora, quien vive en Sevilla, habla muy claro. quien My teacher, who lives in Seville, speaks very clearly. Extra information about a person.
Los estudiantes, quienes llegaron tarde, perdieron la explicación. quienes The students, who arrived late, missed the explanation. Plural people.
La persona con quien hablé fue muy amable. con quien The person with whom I spoke was very kind. After a preposition.
El hombre de quien te hablé está aquí. de quien The man I told you about is here. Preposition + person.

El que, la que, los que, las que

El que, la que, los que and las que are often used after prepositions or when Spanish needs to clarify gender and number.

Spanish example Form English meaning Why this form?
El tema del que hablamos es difícil. del que The topic that we talked about is difficult. Preposition + article + que.
La empresa para la que trabajo es grande. para la que The company I work for is large. Refers to feminine singular noun.
Los documentos a los que me refiero están aquí. a los que The documents I am referring to are here. Refers to masculine plural noun.
Las razones por las que lo hice son personales. por las que The reasons why I did it are personal. Refers to feminine plural noun.

Lo que: referring to an idea

Lo que usually means “what” or “the thing that”. It does not refer to a specific masculine noun. It often refers to an idea, statement, situation or entire clause.

Spanish example English meaning What lo que refers to
No entiendo lo que dices. I do not understand what you are saying. The content of what is said.
Lo que necesito es tiempo. What I need is time. The thing needed.
Eso es lo que me preocupa. That is what worries me. The situation or idea.
Lo que pasó ayer fue extraño. What happened yesterday was strange. The whole event.
Practical rule: use lo que when the relative clause refers to an idea, not to a specific noun.

Cuyo, cuya, cuyos, cuyas: possession in relative clauses

Cuyo expresses possession and agrees with the thing possessed, not with the owner. It is more formal than many other relative structures, but it is important in written Spanish.

Spanish example Possessed noun English meaning Agreement
El escritor cuyo libro ganó el premio vive aquí. libro The writer whose book won the prize lives here. cuyo agrees with masculine singular libro.
La mujer cuya hija estudia medicina es mi vecina. hija The woman whose daughter studies medicine is my neighbour. cuya agrees with feminine singular hija.
Los países cuyos gobiernos firmaron el acuerdo participan. gobiernos The countries whose governments signed the agreement participate. cuyos agrees with masculine plural gobiernos.
Las empresas cuyas oficinas están en Madrid crecieron. oficinas The companies whose offices are in Madrid grew. cuyas agrees with feminine plural oficinas.

Donde: relative clauses about place

Donde introduces a relative clause about place. It often corresponds to “where” in English.

Spanish example Antecedent English meaning Structure
La ciudad donde nací está en el norte. la ciudad The city where I was born is in the north. Place + donde + clause.
El restaurante donde cenamos era excelente. el restaurante The restaurant where we had dinner was excellent. Place + donde + clause.
La casa donde vive es antigua. la casa The house where he/she lives is old. Place + donde + clause.

Restrictive and non-restrictive relative clauses

Spanish relative clauses can either identify which person or thing you mean, or add extra information. This difference is shown with commas.

Type Spanish example Meaning Comma rule
Restrictive Los estudiantes que llegaron tarde perdieron la explicación. Only the students who arrived late missed it. No commas.
Non-restrictive Los estudiantes, que llegaron tarde, perdieron la explicación. All the students arrived late and missed it. Commas add extra information.
Restrictive El libro que está sobre la mesa es mío. The specific book on the table is mine. No commas.
Non-restrictive El libro, que está sobre la mesa, es mío. The book is mine; it happens to be on the table. Commas mark added information.
Comma rule: no commas identify; commas add extra information.

Prepositions before relative pronouns

When a verb or expression requires a preposition, the preposition often appears before the relative pronoun in careful Spanish. This is common with de que, con quien, para la que, por los que and similar structures.

Expression Spanish example English meaning Structure
hablar de El tema del que hablamos es importante. The topic we talked about is important. de + el que → del que
trabajar para La empresa para la que trabajo es internacional. The company I work for is international. para + la que
referirse a Los datos a los que me refiero están aquí. The data I am referring to is here. a + los que
contar con La persona con quien cuento está ocupada. The person I count on is busy. con + quien
luchar por Las razones por las que luchamos son claras. The reasons we fight for are clear. por + las que

Relative clauses: indicative or subjunctive?

In Spanish relative clauses, the indicative is used when the person or thing is known, specific or real. The subjunctive is used when the person or thing is unknown, desired, non-specific or does not exist.

Indicative: known or specific Subjunctive: unknown or non-specific Difference
Conozco a alguien que habla español. Busco a alguien que hable español. Known person vs person being searched for.
Tengo un libro que explica esto. Necesito un libro que explique esto. Known book vs desired book.
Hay una solución que funciona. No hay una solución que funcione. Existing solution vs no existing solution.
Vivo en una ciudad que tiene playa. Quiero vivir en una ciudad que tenga playa. Real city vs desired city.

Where does the relative clause go in a Spanish sentence?

A relative clause should normally be placed as close as possible to the word it describes. If it is too far away, the sentence can become unclear.

Clear structure Less clear structure Why?
Vi al profesor que enseña español. Vi al profesor ayer que enseña español. The relative clause should stay close to profesor.
Compré el libro que me recomendaste. Compré el libro ayer en la tienda que me recomendaste. The second version could refer to the shop, not the book.
Conocí a una mujer que trabaja en Lima. Conocí en Lima a una mujer que trabaja allí. Both can work, but the first is simpler.

Typical mistakes with Spanish relative clauses

  • Placing the relative clause too far from the noun: keep the relative clause close to the word it describes.
  • Using quien for things: quien refers to people, not objects.
  • Confusing que and lo que: use que after a noun, but lo que for “what” or “the thing that”.
  • Forgetting prepositions: Spanish often keeps the preposition before the relative pronoun: del que, con quien, para la que.
  • Ignoring commas: commas can change whether the clause identifies or only adds information.
  • Using indicative for unknown antecedents: busco a alguien que hable, not busco a alguien que habla.
  • Using cuyo without agreement: cuyo agrees with the possessed noun, not with the owner.
