The concept of the enemy stereotype, which is permanently present in colloquial, journalistic, and academic discussions, has not been scientifically analysed so far. In this article, an attempt to provide a definition of “the enemy stereotype” as an independent linguistic being has been made. The stages of this term taking shape in the political reality have also been presented. The article has strictly theoretical nature, and is based on scientific achievements in the fields of research related to stereotypes and hostility. In the author’s opinion, the analysis of the phenomenon of stereotyping carried out from a sociological, psychological, and linguistic point of view is necessary. A reflection on the issue of hostility in general, and on the image of the enemy in political activities in particular is also fundamental.
