What is a relative clause?
A relative clause adds information about a noun, usually introduced by a relative pronoun. In English we say the daughter who studies medicine. In Spanish we use relative pronouns such as que and quien to connect the main clause and the extra information. Relative clauses can be essential (defining) or additional (non-defining).
Defining versus non-defining relative clauses
Defining relative clauses give essential information to identify the noun. For example: La hija que estudia medicina identifies which daughter we mean. Non-defining relative clauses add extra, non-essential information and are set off by commas in Spanish when using quien or con quien. For example: María, que es amable, ayuda a todos. Notice that in Spanish non-defining clauses can also use que, but punctuation and context are important.
Using que with hija
The most common relative pronoun is que. It can refer to people, animals, or things. With hija, which is feminine singular, you usually say La hija que estudia medicina. Here que introduces a clause that tells us which daughter. The verb in the clause must agree with the subject of the clause, not with hija unless they are the same person.
Examples:
La hija que estudia medicina vive en Madrid.
La hija que habla con el profesor es muy responsable.
In both examples que connects hija to the action. The verb estudia agrees with the subject of the relative clause, which is implicitly la hija.
Placement of the relative clause
Typically the relative clause follows the noun it modifies. This is different from some English structures where you might place the clause earlier. In Spanish: La hija que estudia medicina está en la universidad. Never split the noun and its defining clause by putting the clause too far away; it should directly follow the noun for clarity.
When to use quien instead of que
Quien (and its plural quienes) is used specifically for people and is often used after prepositions or when the clause is non-defining. For example, after the preposition con you use con quien: La hija con quien trabajo quiere estudiar medicina. However, for simple defining clauses without a preposition, que is very common and natural: La hija que estudia medicina.
Examples to compare:
La hija que estudia medicina tiene talento. (defining, que)
La hija, quien vive en Madrid, viene mañana. (non-defining, quien and commas)
La hija con quien hablé es la que estudia medicina. (after preposition con, use quien)
Quien versus que: usage tips
Use que for most everyday sentences and when you want a concise defining clause. Use quien when you need a formal tone, when the relative pronoun follows a preposition, or when you want to emphasize that you are referring to a person. Remember that quien must agree in number: quien (singular) and quienes (plural).
Agreement and verb conjugation in relative clauses
The verb inside the relative clause agrees with the clause subject. If the relative clause refers back to la hija, the verb is third person singular. If the clause refers to a plural noun like las hijas, the verb becomes third person plural.
Examples:
La hija que estudia medicina tiene exámenes mañana. (estudia — singular)
Las hijas que estudian medicina tienen exámenes mañana. (estudian — plural)
When the relative pronoun stands for a direct object, the verb still agrees with the subject of the relative clause. For instance: La hija que viste hoy es mi prima. Here viste is the verb for the relative clause and refers to the subject of that clause, not to hija directly; context clarifies the roles.
Past and future tenses in relative clauses
You can use any tense inside a relative clause depending on when the action happens. For example:
La hija que estudió medicina trabaja en un hospital. (past)
La hija que estudiará medicina viajará a estudiar fuera. (future)
Make sure the tense conveys the intended time frame relative to the main clause.
Omitting the relative pronoun and other shortcuts
In some colloquial Spanish sentences, the relative pronoun can be omitted when it is functioning as a direct object. For example: La hija (que) conoces es mi amiga. Both are common, and omitting que often sounds more informal and fluid. However, when the relative pronoun is the subject of the relative clause or follows a preposition, you cannot omit it.
Examples where omission is possible:
La hija (que) conoces viene mañana. — common and natural
Examples where omission is not possible:
La hija que estudia medicina es inteligente. — cannot omit que because it introduces the subject of the clause
La hija con quien hablé es muy amable. — cannot omit quien after preposition con
Possessive and descriptive variations with hija
You can combine relative clauses with possessives or additional descriptive adjectives to add nuance. For instance, show family relationships or qualities:
Mi hija que estudia medicina es la mayor. (distinguishes this daughter from others)
Su hija, que estudia medicina, ganó una beca. (non-defining, extra information)
La hija de mi hermano que estudia medicina vive cerca. (defining which niece)
Note how punctuation and possessives change meaning. With commas the clause is incidental; without commas it defines which daughter or niece you mean.
Examples with different pronouns and structures
La hija que estudia medicina quiere ser cirujana.
La hija de Ana, que estudia medicina, viene el sábado.
La hija cuyos padres son médicos también quiere estudiar medicina. (whose — cuyos agrees in gender and number with the noun it modifies)
In the last example we used cuyo/cuya/cuyos/cuyas to express possession within a relative clause. Cuyo must agree with the thing possessed, not the possessor: La hija cuyos padres son médicos focuses on the parents as the possessed item.
Cultural and usage notes
In many Spanish-speaking cultures family relationships are important, and speakers often use relative clauses to identify which family member they mean. For example, when someone says La hija que estudia medicina, listeners will often infer context such as pride, career expectations, or family support. In formal writing and speech, maintaining clear punctuation with non-defining clauses is more common, while everyday conversation favors shorter, more fluid structures.
Also be aware of regional preferences. Some dialects may prefer quien in certain contexts or omit relative pronouns more freely. Exposure to native speakers through media or conversations helps you internalize these variations.
Common mistakes to avoid
Mixing up que and quien after prepositions. Remember: after a preposition use quien or el que/la que. For example, use con quien or con la que, not con que when referring to people.
Avoid wrong verb agreement. Match the verb to the subject inside the relative clause (la hija estudia vs las hijas estudian).
Misplacing commas. Commas change meaning for defining versus non-defining clauses.
Putting it all together: useful sentence patterns
Here are several common patterns you can reuse when talking about family and education.
La hija que estudia medicina + verb describing main clause.
Example: La hija que estudia medicina trabajará en el hospital local.
Mi hija, que estudia medicina, + extra comment.
Example: Mi hija, que estudia medicina, está muy ocupada este semestre.
La hija de X que estudia medicina + identification.
Example: La hija de mi amiga que estudia medicina acaba de recibir una beca.
La hija con quien + verb after preposition.
Example: La hija con quien hablé anoche me explicó su plan de estudios.
Conclusion
Relative clauses with La hija que estudia medicina illustrate key Spanish grammar points about que, quien, verb agreement, punctuation, and possession. Use que for most defining clauses, choose quien after prepositions or in formal non-defining clauses, and keep verb agreement with the clause subject. With practice you will comfortably add detail to sentences about family, studies, and more, sounding natural in both written and spoken Spanish.
