Etymology
the word diarrhoea originates from the greek 'diarrhoia', a compound of 'dia-' meaning "through" and 'rhein' meaning "to flow." this was adopted into late latin as 'diarrhoea' before entering middle english via medieval latin. the term's literal meaning, "a flowing through," provides a direct and vivid anatomical description of the condition's primary symptom. this greek-based medical terminology has remained remarkably stable in form and logic across centuries of scientific use.
