Relative pronouns in Spanish include “que” (that, which, who), “quien” (who), “cuyo” (whose), “el cual” (which, who), “la cual” (which, who), “los cuales” (which, who), and “las cuales” (which, who). These pronouns are used in various contexts and can refer to people, places, things, or ideas. It’s essential to learn how to use them correctly to improve your Spanish language skills.
