Grammatical person

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). A language's set of pronouns is typically defined by grammatical person. First person includes the speaker (English: I, we), second person is the person or people spoken to (English: your or you), and third person includes all that are not listed above (English: he, she, it, they). It also frequently affects verbs and sometimes nouns or possessive relationships.

Number
In Indo-European languages, first-, second-, and third-person pronouns are typically also marked for singular and plural forms, and sometimes dual form as well (grammatical number).

Inclusive/exclusive distinction
Some other languages use different classifying systems, especially in the plural pronouns. One frequently found difference not present in most Indo-European languages is a contrast between inclusive and exclusive "we": a distinction of first-person plural pronouns between including or excluding the addressee.

Honorifics
Many languages express person with different morphemes in order to distinguish degrees of formality and informality. A simple honorific system common among European languages is the T–V distinction. Some other languages have much more elaborate systems of formality that go well beyond the T–V distinction, and use many different pronouns and verb forms that express the speaker's relationship with the people they are addressing. Many Malayo-Polynesian languages, such as Javanese and Balinese, are well known for their complex systems of honorifics; Japanese, Korean, and Chinese also have similar systems to a lesser extent.

Effect on verbs
In many languages, the verb takes a form dependent on the person of the subject and whether it is singular or plural. In English, this happens with the verb to be as follows:
 * I am (first-person singular)
 * you are/thou art (second-person singular)
 * he, she, one, it is (third-person singular)
 * we are (first-person plural)
 * you are/ye are (second-person plural)
 * they are (third-person plural, and third-person singular)

Other verbs in English take the suffix -s to mark the present tense third person singular, excluding singular 'they'.

In many languages, such as French, the verb in any given tense takes a different suffix for any of the various combinations of person and number of the subject.

Additional persons
The grammar of some languages divide the semantic space into more than three persons. The extra categories may be termed fourth person, fifth person, etc. Such terms are not absolute but can refer, depending on context, to any of several phenomena.

Some Algonquian languages and Salishan languages divide the category of third person into two parts: proximate for a more topical third person, and obviative for a less topical third person. The obviative is sometimes called the fourth person. In this manner, Hindi and Bangla may also categorize pronouns in the fourth, and with the latter a fifth person.

The term fourth person is also sometimes used for the category of indefinite or generic referents, which work like one in English phrases such as "one should be prepared" or people in people say that..., when the grammar treats them differently from ordinary third-person forms. The so-called "zero person" in Finnish and related languages, in addition to passive voice, may serve to leave the subject-referent open. Zero person subjects are sometimes translated as "one", although in tone it is similar to English's generic you "Ei saa koskettaa" ("Not allowed to touch", "You should not touch").
