Restrictive Relative Clauses

A restrictive relative clause is a clause that identifies or specifies which noun you are talking about. Without it, the sentence would be vague or mean something different. In Spanish, restrictive relative clauses are never set off by commas, and they almost always use the relative pronoun que.

What "Restrictive" Means

Consider the sentence "The book I bought is good." The phrase "I bought" is restrictive: it tells us which book. If you removed it, the listener would not know which book you meant. Restrictive clauses narrow down the noun to a specific subset.

El libro que compré es bueno.

The book (that) I bought is good.

Without que compré, the listener has no idea which book you mean. That is what makes the clause restrictive.

The Universal Relative: Que

Spanish uses que as the relative pronoun in restrictive clauses for both people and things. Unlike English, which distinguishes "that" from "who," Spanish just uses one word for both.

La mujer que vive aquí es mi vecina.

The woman who lives here is my neighbor.

El carro que está afuera es nuevo.

The car that is outside is new.

This makes que by far the most common relative pronoun in Spanish. If you are not sure which word to use, que is almost always safe in a restrictive clause with no preposition.

Que Cannot Be Omitted

In English you can usually drop the word "that" in restrictive clauses: "The book I bought" instead of "The book that I bought." Spanish does not allow this omission. Que is required.

💡
If you find yourself translating an English sentence with a dropped "that," remember to put que back into the Spanish version. Leaving it out is a common beginner mistake.

No Commas

A defining feature of restrictive clauses is that they have no commas. The relative clause joins directly onto the noun it modifies, with no punctuation break.

Los estudiantes que llegan tarde pierden puntos.

Students who arrive late lose points.

Notice how "students" is narrowed to "students who arrive late." Only those particular students lose points. If you added commas, the meaning would shift entirely.

Subject vs. Object Function

Que can act as either the subject or the object of its clause. Spanish does not change the form at all.

El chico que me saludó es mi primo.

The boy who greeted me is my cousin.

El chico que saludé es mi primo.

The boy whom I greeted is my cousin.

Both sentences are grammatical and the difference is just where que fits into the inner clause.

💡
For restrictive clauses that talk about hypothetical or unknown people and things, you will need the subjunctive. See Subjunctive in Relative Clauses.
