This diploma thesis investigates to what extent anglicisms are present in the Croatian language, that is, in the Croatian media, considering the increasing influence of the English language and globalization. The paper is divided into two parts, the first is theoretical and the second deals with research into the appearance of Anglicisms in the media, their quantity and analysis. The first part defines key concepts such as linguistic borrowing and words of foreign origin and their division. After that, the concept of anglicism, their use and four types of adaptation to which they can be subjected in the Croatian language are defined. The notion of linguistic purism, its history in Croatia, and the current attitude towards words of foreign origin are defined as well in the first part. The second part deals with anglicisms found on the websites of the Croatian news portals Dnevnik.hr and 24sata.hr. The paper deals with their analysis, adaptation to the Croatian language, and the found anglicisms are compared with the Croatian web corpus and the extent to which they are used in other domains, on other websites, forums and blogs, that is, in the actual use of the language. The research showed that anglicisms are widespread both in the media and in the Croatian web corpus, and some of them have been adapted, while those that are more recent retain their original form.
