The main feature of this edition is the rendering and analysis of similar concepts through a lexicographic term or, conversely, achieving cognitive coherence of multiple expressions through focusing on a lexicographic term. It is obvious that this is not a simple dictionary, given that medical terms are not only interpreted but also explained in a concise and comprehensive manner. At the same time, the existence of an index allows for its use as a Greek-English dictionary. In today's era, where the use of English terminology, especially in medicine, is a daily practice and necessity, the publication of such a dictionary becomes more relevant than ever.
