There has been a lot of research done on the topic of emotions and their somewhat inexplicable connection to language. The many languages in existence pave the way of communicating the emotions as a part of the world that surrounds us. Research into emotional expression and languages has provided many interesting results in the field of psycholinguistics and some of the studies also included swearing as a powerful emotional expression. This particular research focuses on speakers of Croatian whose second language is English and their emotional expression through swear words in both languages. The aim of this study was to explore the nature of the relationship between the participants and their native language Croatian as well as their relationship to English. There is also a significant amount of research on the topic of swearing, but very little from the perspective of the speakers of Croatian. The study focused on researching participants’ feelings when swearing as well as comparing the results with the results of other research studies done on the same topic. The results of the conducted study lead to some interesting conclusions which point to the strength of the relationship between participants and their native language. Moreover, the study shows that the research done on this particular topic can be rather inconclusive. Even though the majority of the results indicate that the participants prefer swearing in their native language, there were many who chose to stay neutral as well as a surprisingly large number of those that claimed that emotional expression is sometimes easier in English.
