It is shown how metaphorical expressions referring to speech and music in George Orwell's 'Nineteen Eighty-Four' contribute to the elaboration of the theme of dehumanization. Metaphor, including metonymy and synecdoche, results from grammatical and lexical choices, and therefore must be addressed on the lexicogrammatical level. A linguistic analysis of clause types shows that Orwell makes consistent grammatical selections to express central meaning. It appears that metaphors are the domains of animals, physical force, and liquids. Although superficially unrelated, they are united in the abstract domain of "control" and play roles in creating the picture of a world in which individual consciousness and liberty have no place. Conventional and creative metaphors harmoniously cooperate in establishing the meaning of dehumanization as a characteristic of the world depicted in the novel.
