It's All Relative

Relative pronouns are a type of word that is easier to recognize in a sentence than to define. So here's an example: In the sentence "Did you see the car that I bought?" the relative pronoun is "that." And in the Spanish equivalent, "¿Viste el coche que compré?" the relative pronoun is que. Que is by far the most commonly used relative pronoun in Spanish, often serving as the equivalent of "that," "which" or "who."
