Today I have for you a chart that lays out the different personal pronouns, hopefully in an easy-to-read format.
Pronouns take the place of a noun. Personal pronouns are a category of pronoun that include subjects, direct and indirect objects, and reflexive object/subjects (when the subject and the object are the same). These pronouns stand in for nouns, such as a name or label which refer to a person, persons or neuter (i.e., it or its).
Strictly speaking, possessive pronouns are their own type of pronoun and in their short form (mi, tu, su etc) actually function as adjectives. However, possessive pronouns, in my opinion, belong in this chart because they indicate to whom something belongs and therefore are pronouns of a personal nature.
At any rate, as always, I hope this chart helps you on your journey as you learn Spanish.
¡Feliz aprendizaje!
