Specificity of representation of the concept sepsis in history of the medical term

The article is devoted to frame analysis of the concept sepsis, to its representation in medical discourse. The concept under research is one of the most difficult and serious linguistic and medical problems due to deficiency of precisely-defined and system-forming terminology in modern medicine. The data of the research is a corpus of definitions of the term which represent the concept analysed at different stages of development of knowledge about sepsis. The analysis revealed four subframes of the concept sepsis reflecting the relevant stages of its development, represented in explicative contexts of the term. Theoretical tenets form a theoretical basis for data analysis.
