The main aim of this thesis is to discuss occurrences of swearwords in the Czech subtitles for the American TV series 'Friends' found on the streaming service HBO Max and to demonstrate that the subtitles go against the general practice among subtitlers to tone swearwords down or delete them. The theoretical part contains a brief general chapter on subtitling, a chapter on swearwords, and a chapter which discusses the universal practice among translators of subtitles when dealing with swearwords. The analysis discusses selected examples of the noted occurrences of words. The examples are discussed in three big categories: 1) swearwords and other pejoratives (the main category); 2) instances of slang, dialects, and colloquial language; 3) references to the LGBT community.
