The thesis deals with Emma Donoghue’s novel titled "Room". The first part of the thesis introduces the author, the novel and the main topic of the book as well as its source of inspiration. It further provides the practical translation of the linguistically most striking and relevant parts of the novel, applying the method of functional equivalence. The second part analyses the lexical aspects, such as the translation of intended grammatical errors and onomatopoetic words, discussing the issues of collocations and synonyms. On the syntactic level, the issue of word order will be discussed. A further subject of the analysis will also be the translation of the style to the target language. Finally, the work closes with a comparative analysis of some selected parts of the official translation based on the established translation theories. The theses aims not only to provide a good and creative translation of linguistically relevant parts of the novel, maintaining the same style and effect on the reader in the target language, but also to relate the lexical and stylistic choice to the theory. For the practical part, I will design a corpus consisting of two columns, left the original text, right the translation. The corpus will contain parts of the book that best represent the research issues. In the corpus, the relevant lexical, syntactic and grammatical parts - (intended grammatical errors typical for baby talk, onomatopoetic words, rhymes, new-creations) will be marked and selected for further analysis. The corpus will be followed by an analysis of the excerpted language that will first be classified and consequently analyzed on the bases of secondary literature. Finally, some of the discussed parts of the translation will be compared with the official translation.
