4.2.2 Pronouns
Pronouns are used to avoid repeating nouns and to supply the subjects for verbs. I, me, we and us are known as the first person pronouns; you is the second person pronoun; and he, him, she, her, it, they and them are third person pronouns in English. In Latin, pronouns are used only when really necessary for the sense of a sentence, or sometimes for emphasis. Often, a pronoun subject, such as I, you or she, can be understood from the ending of the verb. This and that can also be used as pronouns, both in English and in Latin.
