Pronouns, such as "he" and "she," take the place of nouns. They eliminate redundancy.
EXAMPLE"Mary is my friend. Mary is nice. Mary is tall" sounds longwinded. Instead, we would say, "Mary is my friend. She is nice and tall." In Spanish: "María es mi amiga. Ella es simpática y alta."
You will only need to learn certain pronouns in order to speak Spanish for your profession. They are all singular.
Yo is first person. When speaking of yourself, you use first person. When speaking about others, you use third person. Therefore, usted, ella, and él are all third person.
One more note about pronouns in Spanish is that you do not always have to use them. You should use them if your subject is unclear; however, once the subject is clear, you may omit the pronoun. This is very different from English.
EXAMPLEIn English, you must say, "He speaks French. He is from France. He is tall." You cannot leave off the subject pronouns. In Spanish, you can say, "Él habla francés. Es de Francia. Es alto." We only used the word "él" once, but we still made three complete sentences. Likewise, "Yo hablo español" and "Hablo español" both mean "I speak Spanish," even though the word "I" only appears in the first sentence.
Still, pronouns are very important in Spanish. Without them, we would not know how to choose the correct form of the verb to create agreement.
