In linguistics, grammatical person is the grammatical distinction between deictic references to participant(s) in an event; typically the distinction is between the speaker (first person), the addressee (second person), and others (third person). First person includes the speaker (English: I, we, me, and us), second person is the person or people spoken to (English: you), and third person includes all that are not listed above (English: he, she, it, they, etc.) Grammatical person typically defines a language's set of personal pronouns. It also frequently affects verbs, and sometimes nouns or possessive relationships.
