Etymology
The term 'pathogenesis' is a modern scientific compound formed directly from Greek elements to precisely describe a medical concept. The first element, patho-, derives from the Greek pathos, which broadly encompassed suffering, experience, or misfortune, and in medical terminology narrowed to specifically mean 'disease'. The second element, -genesis, comes from the Greek genesis, meaning 'origin' or 'birth', related to the verb gignesthai ('to be born'). Thus, the word's literal construction is "the origin or coming-into-being of disease," which perfectly captures its modern meaning: the biological mechanism and sequence of events that lead from an initial cause to the manifestation of a pathological condition.
Analysis
