In Spanish, pronouns are used to replace nouns in order to avoid repetition. The pronoun 'ellos' is commonly used when referring to a group of people or things that includes both males and females. It is equivalent to the English pronoun 'they'.
For example, if you want to say 'They are my friends', you would say 'Ellos son mis amigos' in Spanish. In this sentence, 'ellos' replaces the noun 'mis amigos' (my friends) to avoid repeating it.
It's important to note that the pronoun 'ellos' is only used for groups of people or things that include at least one male. If you are referring to a group of only females, you would use the pronoun 'ellas' instead.
