Spanish Relative Clauses: Describing Known and Sought-After People or Things

In this lesson, you will choose between indicative and subjunctive in relative clauses according to how the speaker presents the referent. A known, identified, or asserted person or thing commonly takes the indicative. A person or thing that is being sought and whose existence or identity is not confirmed commonly takes the subjunctive.

Known or identified referent: indicative

— I know a person who speaks Japanese.
— I have a computer that works very well.
— There is a store that opens on Sundays.

The speaker presents each referent as existing and identifiable within the conversation.

Sought-after or unconfirmed referent: subjunctive

— I am looking for a person who speaks Japanese.
— I need a computer that works well.
— We are looking for a store that opens on Sundays.

The speaker defines the type of person or thing needed without confirming a specific existing referent.

Compare the same noun phrase

Known:

— I have a teacher who explains very well.

Sought:

— I want a teacher who explains very well.

The noun is similar, but the speaker's relationship to the referent changes.

Indefinite article does not automatically trigger subjunctive

Indicative:

— I know a café that has a large terrace.

The noun is indefinite, but the speaker clearly asserts that the café exists.

Definite article does not automatically force indicative

Context can still make the referent unconfirmed.

— I am looking for the document that has the director's signature.

The speaker may know there is a set of documents but not yet know which one satisfies the condition.

Negative existence can also favor subjunctive

— I do not know anyone who can help me.

The speaker does not identify an existing person with that property.

Known person, unknown property?

If the person is known and the clause gives factual information:

— I am looking for Carlos, who works at reception.

Carlos is a specific known person. The relative clause adds factual information about him.

Search notice examples

— We are looking for someone who has experience with customers.
— We need an apartment that is near the metro.
— We want a company that can start this month.

Do not reduce the rule to definite versus indefinite

The critical question is how the speaker presents the referent: known and asserted, or sought and not yet identified.

A practical relative-clause method

Identify the noun described by the relative clause.
Ask whether the speaker presents a specific existing referent as known or established.
Use the indicative for familiar factual descriptions of known or asserted referents.
Use the subjunctive for a sought-after or unconfirmed referent in the target pattern.
Do not choose the mood only from un / una or el / la.
Use the speaker's intent and the status of the referent as the main guide.

From Relative Clauses to Search Notices

You can now describe something known or specify the kind of person or thing you are still looking for. The next lesson asks you to read search notices for people, services, and accommodation and extract the stated requirements accurately.
