Forms
jeûner[1] Old French jeüner, jejuner, juner and geüner.[1][2][3]
Etymology
It is inherited from Old French jeüner,[1][3] inherited from Ecclesiastical Latin iēiūnō (“to fast, abstain from food”),[4][5][3][6] which in Christian Latin also meant “to go without, keep away from”.[4][5] The Latin verb is derived from iēiūnus (“fasting, hungry”),[5][3][1] also “lean, dry, poor”;[5] Rey connects it with ientō (“to breakfast”), a popular word of unclear origin.[5]
Cognate with Romanian ajuna, Italian digiunare, Occitan junar, Catalan dejunar, Spanish ayunar and Portuguese jejuar.[7]
Earliest recorded meaning
Philippe de Thaon's Comput (1119) uses it for abstaining from food out of penance.[4][8]
Semantic evolution
Outside religion the verb meant simply “to go without food” by about 1160, in the Eneas.[4][5] From the early 13th century, in the Reclus de Molliens, it was also used figuratively, “to deprive oneself of something”;[4][8] Rey dates from 1225 the sense “to abstain from all pleasures”, now literary except in the familiar sense “to be chaste”.[5] The causative faire jeûner ses domestiques is found in Voltaire.[8]
The noun jeûne (14th century, earlier juïne about 1100) and jeûneur (1546) were formed from the verb.[5] The Latin adjective survived in the old adjective jeun (1174), which went out of use in the 16th century, probably because its feminine could be confused with jeune; it remains only in the phrase à jeun “on an empty stomach” (1216).[5]
