The subject of this paper are anglicisms in Croatian computer terminology. In the introductory part, we speak about language borrowing, different types of language borrowing and we are listing several kinds of foreign words that appear in the Croatian language. Further, we describe the four levels of adaptation of anglicisms in the Croatian language following the methodology of Anja Nikolić-Hoyt which was previously defined by Rudolf Filipović. After a brief review of the state of Croatian computer terminology, we are moving onto the analysis of a list of loanwords collected from the BUG magazine, published between January and August 2018. We have analyzed 14 words in total for which we have listed a definition and a short analysis of the level of their adaptation in the Croatian language – either on the phonological, orthographic, morphological or semantic level, depending on the form in which the word appears in the corpus. The analysis also lists the Croatian equivalents that should be used instead of the anglicisms found in the corpus.
