The impact of mass media on social communities has never been more prominent and mass communication more widespread than nowadays. New media have become main communication tools; technological progress has enabled an easier development of telecommunications, simplified trade and transport, and contributed to the development of telecommunication science and science in general. The globalisation process started with the aim of connecting the market of business, economy and economics at the global level in order to liberalise financial market, but today we are witnessing that the globalisation has affected the communications, language, culture, ecology, science and many other social life spheres. The disappearance of borders at political and economic level has, among other this, highlighted one language as the language of the globalised world. The English language has become the language of world’s communication i.e., the language of globalisation which has favoured the increasing influence of English on other languages. The increasing spread of the English language or the so called anglicisation of other national languages, has had negative consequences, i.e., has endangered “minor languages” and caused the mixing of language elements belonging to various language codes, and the use of original English words although a well-established and accepted word exists in the national language. For this reason, recent research has been intensively focusing on how and at what levels the English language affects the Croatian language (and other national languages), which is the topic of this thesis. It is the aim of this thesis to research and analyse the linguistic elements of the English language used in the youth magazine “OK” and to determine the situations in which English words are used in this magazine. The first chapter includes the key concepts referring to globalisation and provides a brief overview of the dominant role the English language has assumed as an unofficial language of international communication. The second chapter is dedicated to mass communication and the importance of media literacy in modern times, and shows the errors made in the use of English in public communication. In the last chapter, the research results are presented.
