The Complete Guide to Medical Etymology: Where Anatomy and Clinical Words Really Come From
Over 90% of formal medical terminology derives from Latin and Greek — the highest proportion of any professional domain. Cardiology comes from Greek “kardia” (heart); diagnosis from Greek “dia + gnosis” (knowing through); hospital from Latin “hospes” (guest). Every body part, disease, procedure, and drug has a name built from predictable ancient components. This guide decodes the system — once you know 200 roots, you can read almost any medical term.
