<P> 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 . </P> <P> 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," but the problem with that is that English language constructions involving one, e.g. "One hopes that will not happen," are rare and could be considered expressive of an overly academic tone to the majority of people, while Finnish sentences like "Ei saa koskettaa" ("0 cannot touch" or "it is impossible to touch") are recognizable to and used by young children in both languages . </P>
