Pronoun

In modern English, pronouns can function as substitutes for both proper and common nouns. For example, "me," "you," "he," "they", "this," "myself," "themselves," are all pronouns. Within functional linguistics, however, pronouns are described as a separate set of words, since pronouns in English have additional functions beyond those of ordinary nouns; for instance the pronoun "who" has an objective case, "whom," whereas ordinary nouns in English no longer take this case.
