Relative pronouns: el que, quien, las que...

What these relative pronouns do (in real life)

They let you refer back to a person or a thing without repeating the noun.

• el / la / los / las que = “the one(s) that / which” (people or things)
• quien / quienes = “who” (people only, often more formal)

Step 1: Is it a person or a thing?

• Thing / object / concept → use el/la/los/las que
• Person → you can use el/la/los/las que OR quien/quienes (more formal)

Step 2: Is the noun written, or “understood” from context?

• Noun is present (you name it) → sustantivo + el/la/los/las que or sustantivo + quien/quienes
• Noun is not present (you mean “the one(s)”) → el/la/los/las que or quien/quienes alone

Step 3: Agreement check (the most common mistake)

el / la / los / las must match the noun you refer to (gender + number).

• la receta → la que ✅ / el que ❌
• los folletos → los que ✅ / las que ❌
• el médico → el que ✅
• las pastillas → las que ✅

When “quien/quienes” sounds better (and why)

• Use quien/quienes for people, especially in a more professional tone.
• It is common in written Spanish and more formal speech.

Compare:

• El farmacéutico, quien me atendió, me explicó la dosis. (more formal)
• El farmacéutico, el que me atendió, me explicó la dosis. (more neutral, still correct)

Prepositions: don’t drop them (con, a, de, en…)

If the idea requires a preposition in English, Spanish usually keeps it before the relative.

• “with which” → con el/la/los/las que
• “to whom” → a quien / al/a la que
• “from which” → de la que, del que, etc.

Examples:

• Necesito la receta con la que voy a la farmacia.
• Es el paciente a quien llamaron primero.
• Este es el informe del que hablamos.

Quick self-check (30 seconds before you answer)

1. Person or thing? (thing → el/la/los/las que; person → quien/quienes or el/la/los/las que)
2. Do I say the noun or is it “the one(s)”?
3. Agreement: el/la/los/las matches gender + number.
4. Preposition: con/a/de/en + relative if needed.
