Questions & Answers about Los instructores, los cuales enseñan la postura, suelen corregir los errores.

Why use los cuales here instead of just que or quienes?

You can absolutely use que or quienes here! In fact, que is much more common in everyday speech. However, los cuales (and its other forms like el cual or la cual) is often used in formal Spanish and written texts to mean "who" or "which." It adds a touch of formality to this sentence.

Do I have to use the commas around los cuales enseñan la postura?

Yes, the commas are required here if you use los cuales. This is a non-defining clause, meaning it just adds extra background information about the instructors rather than specifying which instructors we mean. When acting as a subject, el cual and its variations can only be used in these comma-separated clauses. If you removed the commas to specify only the instructors who teach posture, you would have to use que.

How do I know whether to use el cual, los cuales, or las cuales?

The relative pronoun has to match the gender and number of the noun it refers back to (its antecedent). Here, it refers back to los instructores, which is masculine and plural. Therefore, you must use the masculine plural form: los cuales.
