This master's thesis deals with the translation of phraseological units from English into Croatian and the challenges that arise during the process. The translation of phraseological units is always a challenge for translators because of cultural differences between a source and a target language. Since the goal of every translation is the transfer of as many features as possible of the original text into the target text, translators aspire to translate every phraseological unit with a unit of the same type into the target language. Due to cultural differences, it is not always possible to find an equivalent phraseological expression in the target language, which is why there are different approaches and strategies of translation when it comes to phraseological units. The fundamental aim of this master's thesis is to examine the practices of translation by investigating which translation strategies are used most frequently when it comes to phraseological units, as well as to evaluate the translator’s choices, and to provide alternative strategies that could or should have been used in order to achieve a successful translation. The corpus of this thesis is based on the first five episodes of the fifth season of the British reality show Love Island, since it provides a variety of phraseological units. For the purposes of the analysis of this thesis, the PUs of the source language were grouped according to Fiedler’s conventional types, while their translations were analyzed according to the translation strategies by Baker. This master’s thesis provides a demonstration of the challenging task of translating phraseological units due to their cultural and social boundedness which proves that it is necessary to understand the characteristics and features of phraseological units in order to find their adequate translation.
