pathogenesis

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.

Structure: patho (disease) + genesis (origin, creation) - patho: From Greek pathos, meaning "suffering, disease". It functions as a combining form indicating a relationship to disease. - genesis: From Greek genesis, meaning "origin, creation, source". It functions as a noun-forming suffix indicating a process of coming into being.
