Chinese pronouns (Chinese: 代词/代詞; pinyin: dàicí or Chinese: 代名詞; pinyin: dàimíngcí) differ somewhat from pronouns in English and other Indo-European languages. For instance, there is no differentiation in the spoken language between "he", "she" and "it" (though a written difference was introduced after contact with the West), and pronouns are not inflected to indicate whether they are the subject or object of a sentence. Mandarin Chinese further lacks a distinction between the possessive adjective ("my") and possessive pronoun ("mine"); both are formed by appending the particle 的 de. Pronouns in Chinese are often substituted by honorific alternatives.
