The T–V distinction is the contextual use of different pronouns that exists in some languages and serves to convey formality or familiarity. Its name comes from the Latin pronouns tu and vos. The distinction takes a number of forms and indicates varying levels of politeness, familiarity, courtesy, age or even insult toward the addressee. The field that studies and describes this phenomenon is sociolinguistics. Many languages lack this type of distinction, instead relying on other morphological or discourse features to convey formality. English historically contained the distinction, using the pronouns thou and you, but the familiar thou largely disappeared from the era of Early Modern English onward, with the exception of a few dialects. Additionally, British commoners historically spoke to nobility and royalty using the third person rather than the second person, a practice that has fallen out of favour. English speakers today often employ semantic analogues to convey the mentioned attitudes towards the addressee, such as whether to address someone by given name or surname or whether to use sir or madam. Under a broader classification, T and V forms are examples of honorifics. The T–V distinction is expressed in a variety of forms. Two particularly common means are: Addressing a single individual using the second-person plural forms in the language, instead of the singular (e.g. in French). Addressing individuals with another pronoun with its own verb conjugations (e.g. in Spanish). Origin and development The terms T and V, based on the Latin pronouns and , were first used in a paper by the social psychologist Roger Brown and the Shakespearean scholar Albert Gilman. This was a historical and contemporary survey of the uses of pronouns of address, seen as semantic markers of social relationships between individuals. The study considered mainly French, Italian, Spanish and German. The paper was highly influential and, with few exceptions, the terms T and V have been used in subsequent studies. The status of the single second-person pronoun you in English is controversial among linguistic scholars. For some, the English you keeps everybody at a distance, although not to the same extent as V pronouns in other languages. For others, you is a default neutral pronoun that fulfils the functions of both T and V without being the equivalent of either, so an N-V-T framework is needed. History and usage in language In classical Latin, was originally the singular, and the plural, with no
