Abstract
<jats:p>Based on Spanish materials, the monograph examines political discourse as a linguosemiotic way of representing reality, its interpretation and transformation in the environment of Internet communication by means of verbal and non-verbal sign codes. The author identifies and analyzes semiotically polycode communicative units of Internet political discourse — hashtag and post — that operate as textual, metatextual and hypertextual discourse tools. They carry out a semiotic function of meaning transmission, represent information of enhanced semantic density, and eventually denote the dominants of the current political agenda conceptual space aimed at its specific interpretation in mass consciousness. A special modus of political discourse turns speech into a purposeful social action, with the addresser trying to monopolize the function of meaning generation and instill his/her own interpretation of reality. The study of verbal and nonverbal semiotic mechanisms of meaning formation makes a topical area of theoretical and practical discourse research and teaching a foreign language for professional purposes in the ever-evolving environment of Internet communication, which inevitably undergoes changes in the context of dynamic development.</jats:p>
