Etymology
the word 'diagnose' is a modern english back-formation from the noun 'diagnosis'. its core components trace back to ancient greek. the prefix 'dia-' carries the sense of "through" or "apart," while the root 'gnosis' means "knowledge" or "the act of knowing." the literal, ancient greek concept was "to distinguish" or "to discern through knowledge." this logical structure was preserved as the term entered medical and scientific vocabulary via latin and new latin. the modern verb 'diagnose' thus retains this precise logic: it signifies the process of coming to know the nature of a condition by thoroughly analyzing and distinguishing its signs.
