The aim of this work is to disclose stylistic discourse-level features of phraseological units from a cognitive perspective. A discourse-based view allows us to investigate phraseological units in a broader context, not just in single phrases or sentences. It is very important to mention about this vision, as discourse studies tend to overlook stylistic use of phraseological units. For example, “The Handbook of Discourse Analysis” (Schiffrin, 2004) does not deal with phraseology in discourse at all. It is comparably new area about a cognitive approach to stylistic use of phraseological units in discourse. It is, of necessity, an interdisciplinary field, since these issues cannot be addressed through the knowledge resources of any single rule. 
The use of figurative language, including phraseological units, has been recognised as a big part of human cognition, a revealing cognitive mechanism. Recent decades have witnessed increasing interest in various aspects of phraseology, especially after the foundation in 1999 of the European Society of Phraseology (EUROPHRAS), which has become a main part of phraseological research, organising continuous conferences, meetings and other activities.
