Forms
jeun (invariable)[1] Old French jeün, an adjective until the 16th century;[2][3] Anglo-Norman spellings include jun, geun and juin.[4]
Etymology
It is inherited from Old French jeün (“fasting”), inherited from Latin iēiūnus (“having eaten nothing, fasting”), which also meant “dry, meagre, lacking” figuratively.[5][1][6] The phrase is formed with the preposition à.[5]
The adjective went out of use in the 16th century, probably because its feminine was hard to tell apart from jeune “young”; its masculine then survived only as a noun in that phrase.[7][8]
Cognate with Italian digiuno, Occitan jejun, Catalan dejú, Spanish ayuno and Portuguese jejum.[9]
Earliest recorded meaning
The adjective is recorded in 1174 in Guernes de Pont-Sainte-Maxence's Saint Thomas, meaning fasting, not having eaten; the phrase à jeun follows in 1216 in Guillaume le Clerc's Fergus.[5]
Semantic evolution
In Old and Middle French jeün was a full adjective: the Roman de la Rose speaks of serving someone à saoul et à jeün, full and fasting, and Froissart of soldiers who were tous jeuns.[2] After the adjective disappeared, only the adverbial phrase remained.[7][8]
À jeun came to mean with an empty stomach in general (1552, Rabelais),[10] and in the language of the Catholic Church être à jeun meant keeping the fast before communion, having neither eaten nor drunk since midnight (1690, Furetière).[10][2] From 1846, in George Sand, it is used familiarly of a drinker who has not yet had anything to drink that day.[10][8]
