Pronouns are words that take the place of nouns. In Spanish, pronouns are used to refer to third person subjects (singular or plural) when their gender or number needs to be specified. Unlike in English, Spanish pronouns are often omitted because the conjugated verb ending identifies the subject. The major types of Spanish pronouns include those that refer to the first person (yo, nosotros), second person (tu, ustedes, vosotros), and third person (el, ella, ellos, ellas). A chart is also provided listing common Spanish pronouns and notes on their conjugation.
