Forms
lundi m (plural lundis)[1] Old French lunsdi, lunsdis; in north-eastern texts diluns, deluns.[2][3]
Etymology
It is inherited from Old French lunsdi, inherited from Vulgar Latin *Lūnis diēs, an alteration of Latin Lūnae diēs (“day of the moon”) after the genitives Mārtis, Iovis and Veneris (see mardi, jeudi, vendredi).[2][4][3][5] diē Lūnis is attested in Apulia in 393.[2] The parts are lūna (“moon”) and diēs (“day”).[4][6]
In Rome the days of the week were named after the seven planets;[2][4] Christianity replaced Saturn and the Sun by sabbatum and dominicus, the sources of samedi and dimanche.[2][4] The order diēs Lūnae seems to have been the usual one, competing early with the reverse order;[2][4] Isidore of Seville also records a type without the word for day, and a Christian type secunda fēria, kept in Portuguese segunda-feira.[2][4]
The type *diēs Lūnis survives in Catalan dilluns, Occitan dilun and Old French deluns (Wallonia, Hainaut, Picardy), the reverse order in French and Italian lunedì,[2][4] and *Lūnis alone in Spanish lunes and in Romanian and Sardinian.[2][4]
Earliest recorded meaning
It is first recorded as lunsdi in Philippe de Thaon's Comput (1119), and as lundi in Wace's Roman de Rou (1160–1174).[2][4]
Semantic evolution
The word names the first working day of the week, after Sunday.[4] The working week's restart explains ça va comme un lundi “things are not going too well”.[4] Not working on Monday was faire le lundi des savetiers (Oudin, 1656), later faire le lundi (1791) and fêter la Saint-Lundi (1867).[6][7][8] Lundi gras, the last Monday of the carnival, is recorded in 1530 and lundi saint in 1680.[6]
