The function of a pronoun is to replace a noun. Some pronouns can be substituted for nouns. Here are some examples: There is no substitution for Yo-I, because you are doing the speaking.
I am short- Yo soy baja.
No substitution for You- Tú because you are the person being spoken to
Are you American? ¿Tú eres Americano, no ?
ella-she You can substitute él for a boy’s name: Pablo es alto- He the boy(él) is tall.
Mayra es alta. -She the girl(ella) is tall.
When learning how to speak it is very important to learn how and when to use the subject pronouns.
