+ ''Zaeta'' or ''zēta'' appear in the Historia Augusta and in many manuscripts, and Medieval Latin wrote ''diēta''.^(Lewis & Short 1879)^(Niermeyer 1976)
+
+ ==Etymology==
+ It is [[bor|grc|δίαιτα|tr=díaita|t=way of living, regimen; dwelling]], from [[m|grc|διαιτάω|tr=diaitáō|t=to treat; to arbitrate]].^(OLD 2012)^(Wiktionary)^(Köbler 2010)^(Etymonline)
+
+ ==Earliest recorded meaning==
+ The OLD's earliest citation is from Cicero, of a course of medical treatment.^(OLD 2012) Köbler dates Cicero 81–43 BC.^(Köbler 2010)
+
+ ==Semantic evolution==
+ In Cicero it was a regimen, a course of medical treatment, and in Statius and Pliny the Younger a room of a house, and Petronius used it of a ship's cabin.^(OLD 2012)
+
+ Medieval Latin, taking it for a derivative of [[diēs]] “day”, spelled it ''diēta'' and used it for a rule of life, a diet; a daily meal; a day's march; a day's work; the daily liturgy; and a day appointed for a meeting, an assembly.^(Niermeyer 1976)^(DMLBS) British Medieval Latin also had a book on diet, a monastic food allowance and the starvation diet of the ''peine forte et dure''.^(DMLBS) [[en|diet]] “regular food” (about 1200) came through Old French ''diete'', and [[en|diet]] “assembly” (mid-15th century) directly from Medieval Latin ''diēta''.^(Etymonline)
