Language borrowing is present in all languages as a result of various civilizational and cultural contacts. The work mentions the understanding of language in contact and presents a discussion on the concept of language mixing, and the concept of language borrowing is presented in detail. The reasons for its occurence, its types and categories are highlighted. The influence of the English language and American culture on the Croatian language system is then analyzed in more detail, from the initial historical point to the present day. The reasons for such popularity, borrowing and use of anglicisms are highlighted, and examples from everyday language practice are given. The presentation of previous research highlights examples of most commonly used anglicisms and acronyms in the language of young people. Examples of the use of anglicisms in the language practice of kindergarten children are also highlighted. Today, the number of loanwords in the Croatian language system is exceptional. Borrowing is a ´tireless´ process that is constantly present in every language, and the borrowing of words between two languages will always occur. Therefore, it is necessary to find a good balance between necessary and unnecessary loanwords and nurture the native Croatian language, thus preserving it for new generations.
