You've already learned the subject pronouns for singular persons, now we will also learn the subject pronouns for plural persons.
|Personal subject pronouns||Singular||Plural|
|Second person||tú, usted|
|vosotros, vosotras, ustedes|
|Third person||él, ella|
Nosotras, vosotras and ellas refer to groups of only females and nosotros, vosotros and ellos refer to groups of only males or to groups with both males and females.
Tú, vosotros and vosotras are informal forms, used for addressing friends and family. Usted and ustedes are more formal, used for addressing strangers and superiors.
In Latin America, ustedes is generally used instead of vosotros and vosotras, whether addressing friends or strangers. You will only need to use vosotros and vosotras when you go to Spain.
