Philology: scientific researches

Abstract: The article is devoted to using emotional interjections and phraseological interjections as modal words. The object of the research is the interjection as a part of speech. The subject of the research is the functional interjection used as other parts of speech, in particular, modal words. The author of the article analyzes gramatical features of interjections and demonstrate how they are similar to modal words. The author pays special attention to transformational modification of interjection constructs aimed at defining cases when interjections are used as modal words, and determination of semantic constraints when interjections are replaced with modal words. In the course of the research the author has used the following methods: comparative, transformational, contextual and semantic analysis. The scientific novelty of the research is caused by the fact that the author discovers, analyses and interprets situations when interjections function as modal words. As a result of the research, the author makes the following conclusions: interjections can be used as modal words and this is the way the modality of interjections reveals itself; emotional interjections and phraseological interjections are used as modal words; interjections that replace modal words express both an emotional response of a speaker to the world and the shape of his or her thought ingratiating to the meaning of relevant modal words.
