one

> one
one is used in formal situations to indicate an indefinite person where "you" would be used in informal situations, as in "One should not believe all one hears" and "One should be kind to animals". This construction can sound rather affected. Examples of the informal "you" include "You would've thought he would've had more sense" and "You wouldn't think anyone could be so stupid". One when followed by "of the" and a plural noun takes a singular verb, as in "One of the soldiers was killed" and "One of the three witnesses has died". However, the constructions "one of those ... who" and one of the ... that" take a plural verb, as in "He is one of those people who will not take advice" and "It is one of those houses that are impossible to heat".
