Pronunciation

  • UK: /daɪəˈbɛtɪk/[1]
  • US: /ˌdaɪəˈbɛtɪk/[1]

Etymology

It is borrowed from Medieval Latin diabeticus (“a person with diabetes; of diabetes”),[2] formed from Latin diabētēs (“siphon”), in later Latin also the disease, with the suffix -icus.[2] The Latin word is from Ancient Greek διαβήτης (diabḗtēs, “compass, siphon”), from διαβαίνω (diabaínō, “to pass through”), from διά (diá, “through”) and βαίνω (baínō, “to go”).[2][3] The Shorter Oxford and Merriam-Webster instead take the English word from French diabétique,[4][5] recorded in Middle French from the second half of the 15th century,[2] and Etymonline and Dictionary.com treat it as diabetes with the suffix -ic.[3][6][7] The OED compares the earlier diabetical and Italian diabetico.[2]

Earliest recorded meaning

As a noun, the disease diabetes itself, a sense now obsolete: 1660, in J. Harding's translation of Paracelsus.[2] The Middle English medical writer Henry Daniel had already used the Latin form diabetica for the disease in 1379.[2]

Semantic evolution

Etymonline records the adjective diabetical from about 1600.[3] In 1673 diabetic could describe any excessive outpouring, a sense that died out by 1698.[2] The adjective "relating to diabetes" is recorded from 1702, and "affected with diabetes" from 1715.[2][3] The noun for a person with diabetes is recorded from 1763 in the OED,[2] from 1840 in Etymonline and Merriam-Webster,[3][5] and the Shorter Oxford dates both uses to the late 18th century.[4] As diabetes came to mean mainly diabetes mellitus, diabetic followed it;[3][4] it also came to describe foods made with little sugar for people with the disease.[4][8]
