The study of diplomatic discourse is part of the research of specialized languages. This enterprise offers us the opportunity to formulate unique ideas and observations regarding the stylistic structure of the updated language, of the linguistic and cultural relations between different peoples. At the same time, the analysis of terminologies of different fields of activity (in our case - diplomatic), the determination of areas of interference and the relationship with the common language (usage) are the main objectives of current language studies, especially in the direction of language evaluation in terms of its function. Diplomacy, diplomatic language, is a polyvalent science (social, political, economic, cultural, etc.), which has as object of study one of the major components of society, namely the reality of the diplomat. At the same time, diplomacy is a technique operating with a set of rules that organizes human coexistence between states and worlds and establishes its main coordinates, guiding diplomatic-human behavior and defending the interests of society. Diplomacy as a science and as an art is a reality summarized in a Latin saying: iusars est ars acquiet boni ("art is what is fair and useful").
