Word History

Etymology

Middle English diabet, diabete, borrowed from Late Latin diabētēs, borrowed from Greek diabḗtēs, from diabē-, variant stem of diabaínein "to stride, walk or stand with legs apart, step across, cross over" (from dia- dia- + baínein "to step, walk") + -tēs, suffix of agency — more at come entry 1

Note: The literal sense of Greek diabḗtēs in relation to the base verb diabaínein is not entirely clear. The Greek physician Aretaeus of Cappadocia (active ca. 130-40 A.D.), author of a detailed description of diabetes mellitus (in Book 2 of De causis et signis diuturnorum morborum), takes the name of the disorder as a given, and explains it as a particular application of the word diabḗtēs, the meaning of which he seems to regard as self-evident. It has been assumed that he alludes to diabḗtēs in the sense "siphon," referring to frequent urination, as if liquid was being drawn out of the sufferer by a siphon. In the following clause, however, he maintains that moisture (tò hygrón) does not stay in the body but leaves it "as if by a diabáthrē ("hókōs diabáthrēi")." The word diabáthra (Ionic diabáthrē)—also a derivative of diabaínein—has various attested meanings: "ladder," "gangway," "bridge." The suggestion has been made that "bridge" or "channel" is the most appropriate sense, though the mixing of metaphors is perhaps an indication that the text is corrupt, or that some no longer recoverable sense of the word is in play. (See discussion in Chalmers L. Gemmill, "The Greek concept of diabetes," Bulletin of the New York Academy of Medicine, vol. 48, no. 8 [September, 1972], pp. 1033-36.)
