Indirect object pronouns in Spanish are small words that replace the person who receives the action of the verb. They answer the question: 'To whom?' or 'For whom?' something is done.
Use indirect object pronouns in Spanish when you want to say that something is given, told, or done to someone. They are used with verbs like 'dar' (to give), 'decir' (to say/tell), and 'enviar' (to send).
