Lesson 43: Relative pronouns — the full set

Part 1: Why so many relatives?

English collapses most situations onto who / that / which. Spanish spreads the same job across nine form-families. The choice depends on three factors: (1) what we're replacing (person, thing, place, time, idea); (2) is there a preposition in front (con, de, para, en, sin, sobre…); (3) is there a comma — restrictive vs non-restrictive.

Master rule: if que fits — use que. The other pronouns exist for when que breaks (long preposition, formal register, "whose", "what" as an idea).

Part 2: que — the workhorse

Que is the most common relative in Spanish. It works for people and things, in restrictive and non-restrictive clauses, and does not change for gender or number. Think of it as English that / who / which rolled into one word.

Trap: after long prepositions (delante de, detrás de, gracias a, según…) plain que does not work — use el que or el cual. See Part 4.

Note for English speakers: English drops "that" — The book I'm reading… Spanish cannot drop que. The relative is always present.

Part 3: quien / quienes — people only

Quien (singular) and quienes (plural) refer only to people. Use them:

• after a preposition: La chica con quien hablo es Ana.
• in a non-restrictive clause: Mi tío, quien vive en Sevilla, es médico.

In a restrictive clause without a preposition, quien sounds bookish — native speakers say que: La mujer que habla (not la mujer quien habla).

Part 4: el que / la que / los que / las que — after prepositions, for clarity

This series agrees with its antecedent in gender and number:

Use it:

• after long prepositions (delante de, detrás de, gracias a, debajo de, dentro de, junto a…): La mesa debajo de la que está el gato es de madera.
• after any preposition in formal-ish speech: El proyecto sobre el que hablamos…
• to remove ambiguity when more than one antecedent is possible: La hermana de Pedro, la que vive en Lima, llega hoy. (specifically that sister, the one who lives in Lima)
• at the start of a sentence meaning "the one who / those who": El que quiera venir, que venga.

Part 5: el cual / la cual / los cuales / las cuales — formal register

Same logic as el que, but more formal and more written. Rare in casual speech; constant in business documents, academic prose, journalism, legal text.

Use it:

• after prepositions (especially long ones): El acuerdo según el cual trabajamos…
• in non-restrictive clauses in writing: El proyecto, el cual fue aprobado el lunes, comienza ya.
• to remove ambiguity in long, complex sentences.

el que vs el cual: both work after prepositions. El cual is slightly more formal (preferred in academic/legal writing); el que is more neutral (dominates in speech). Note: de + el cual → del cual; de + el que → del que.

Part 6: cuyo / cuya / cuyos / cuyas — "whose"

A possessive relative. Corresponds exactly to English whose.

THE KEY RULE: cuyo agrees with the thing possessed, not with the possessor. El escritor cuyas novelas leo — novelas is feminine plural → cuyas. The fact that escritor is masculine is irrelevant.

Register & traps: cuyo is formal-literary; casual speech often paraphrases (La mujer; conozco a su hija). But NEVER say la mujer que su hija… — this colloquial calque is condemned by grammar. Correct: la mujer cuya hija…. English whose does the same job — Spanish just agrees with the thing.

Part 7: donde — relative for places

Donde is the place relative. No article, no inflection.

Alternative: La ciudad en (la) que nací is also correct. Donde is shorter and more natural.

Part 8: cuando — relative for time

Cuando links a time antecedent to its clause: El día cuando te conocí fue especial. Often preferred: El día en que te conocí fue especial. Both fine.

Part 9: lo que / lo cual — neuter, for ideas

These are neuter relatives. They replace not a noun, but an idea, a situation, or a whole previous clause. English what and which (referring to a whole clause).

Lo que — "what / the thing that". Stands at the start of a phrase, or as the object of verbs like decir, pensar, saber, entender, querer:

• Lo que me molesta es su tono. — What bothers me is his tone.
• No entiendo lo que dices. — I don't understand what you're saying.
• Lo que dices es interesante. — What you say is interesting.

Map this directly to English what as a relative (not as a question word).

Lo cual — "which" referring to a whole clause. Only after a comma, referring to the entire previous statement:

• Llegó tarde, lo cual nos sorprendió. — He arrived late, which surprised us.
• La empresa quebró, lo cual afectó a todos. — The company went bankrupt, which affected everyone.

Difference: lo que can stand at the start of a sentence and means "the thing that". Lo cual stands only after a comma and refers back to the whole previous clause. Both translate as what / which; position and function differ.

Part 10: Restrictive vs non-restrictive — the comma decides

Compare:

• Mis hermanos que viven en Madrid son médicos. — Those of my brothers who live in Madrid are doctors. (implies I have other brothers elsewhere)
• Mis hermanos, que viven en Madrid, son médicos. — My brothers, who (by the way) live in Madrid, are doctors. (all my brothers live in Madrid, and they are all doctors)

In non-restrictive clauses Spanish often prefers quien / el cual / lo cual over plain que — cleaner in writing. English does the same dance — "my brothers who live in Madrid" vs "my brothers, who live in Madrid" — Spanish just has more pronoun options.
