diabetes: [16] Diabetes means literally ‘passing through’; it was originally so named in Greek because one of the symptoms of the disease is excessive discharge of urine. Greek diabétēs was a derivative of diabaínein ‘pass through’, a compound verb formed from the prefix dia- ‘through’ and baínein ‘go’ (a relative of English basis and come). English acquired it via medieval Latin diabētēs. Compare DIARRHOEA. => basis, come[diabetes etymology, diabetes origin, 英语词源]
