This thesis is about the influence of the English language on the Croatian language through different kinds of media or means of communication, which significantly influence everyday communication of young people in society by using new inadequate expressions of English origin. The research is based on samples taken in two Đakovo high schools, the A. G. Matoš Gymnasium and the vocational school Braća Radić. For the purposes of the research, a survey questionnaire was prepared, containing English-Croatian sentences collected by monitoring the domestic media. Students had to identify and translate words of English origin within the sentences of the questionnaire. The purpose of the research is to determine the element of understanding of English words within the population of the children and the young. Words used within the mentioned population group are often shortened versions of English words that they use but do not fully understand. We've come to the conclusion that, today even more than ever before, the influence of the English language has a significant impact on the everyday communication of youngsters, that it is used but not fully understood and also that its influence is substantial in the media and communication altogether. The reason for that is found mainly in the substantial use of the English language in music, movies, sports, internet, TV content and other technological professional terms that have no adequate replacement in the Croatian language, i.e. the English language is constantly being implemented and adapted into its Croatian version on a global level.
