One (pronoun)
（重定向自Impersonal pronoun）
One is a pronoun in the English language. It is a gender-neutral, indefinite pronoun, meaning roughly "a person". For purposes of verb agreement it is a third-person singular pronoun, although it is sometimes used with first- or second-person reference. It is sometimes called an impersonal pronoun. It is more or less equivalent to the French pronoun on, the German man, and the Spanish uno. It has the possessive form one's and the reflexive form oneself.
