Pronunciation

  • IPA (5th-century BC Attic): /dí.ai̯.ta/[1]
  • IPA (4th-century AD Koine): /ˈði.ɛ.ta/[1]
  • IPA (10th-century Byzantine): /ˈði.e.ta/[1]

Forms

δῐ́αιτᾰ (díaita) f (genitive δῐαίτης); first declension[1]

Etymology

It is a back-formation from the verb διαιτάομαι (diaitáomai, “to live”), διαιτάω (diaitáō).[2][3][4] That verb stands beside αἴνυμαι (aínumai, “to take”) as ἀρτάω (artáō) stands beside ἀείρω (aeírō): it meant at first “to take apart, divide”, whence on the one hand “to share out food, feed oneself, live”, and on the other “to decide”, in the legal sense of αἴτιος (aítios).[2][3] Only in the medical sense “to treat as a physician” is διαιτάω (diaitáō) derived from δίαιτα.[2]

Earliest recorded meaning

Its first recorded uses are in Alcaeus, for a life free from toil, and in Pindar.[4][5]

Semantic evolution

In Classical Greek it is a way of life, daily life (Pindar, Herodotus, tragedy, Thucydides), and the means of supporting it.[6] Thucydides and Plato use it for a prescribed regimen for athletes and the sick, and Herodotus, Plato and Xenophon for the kind of food eaten, a diet.[6] It was also a stay or residence, and a room or lodging (Aristophanes, Aristotle).[6] At Athens it was arbitration, and its arbitrator was the διαιτητής (diaitētḗs).[6][2]

Latin borrowed it as diaeta.[7] Modern Greek δίαιτα “diet” is learned;[8] δίαιτα “diet, assembly” is a learned borrowing of Medieval Latin dieta, from Latin dies “day” after German Tag, spelt to match the ancient word.[8]
