Subject pronouns in Spanish include forms to distinguish between informal/formal, singular/plural, and masculine/feminine addresses. The main subject pronouns are: Yo/Nosotros for first person singular and plural, Tú for informal second person singular, Ud. for formal second person singular, Él/Ellos for third person masculine singular and plural, Ella/Ellas for third person feminine singular and plural, and Uds. for formal second person plural. Spanish has multiple options to respectfully address individuals and groups depending on context that English lacks with just "you".
