Pronunciation

Forms

luni f (plural luni)[1] The oldest record writes lune: „Lune, a 11 d[umi]neca” “Monday of the 11th Sunday”.[2] Gaster's chrestomathy also has luri.[3] The articled form lunea means “on Mondays”.[4]

Etymology

It is inherited from Vulgar Latin *lūnis, an analogical form of diēs Lūnae (“day of the Moon”) made after Mārtis and Iovis, the genitives in the names of Tuesday and Thursday.[5][4][6][7] The Latin phrase is a calque of Ancient Greek ἡμέρα Σελήνης (hēmérā Selḗnēs).[1]

The word survives in all four branches: Aromanian luni, Megleno-Romanian luni and Istro-Romanian lur.[5][8][9][10][11] Sardinian lunis and Spanish lunes continue the same form, while Italian lunedì and French lundi continue the full phrase with diēs.[12][6][13]

Earliest recorded meaning

The first record is lune in the Slavonic–Romanian Gospel book of 1551–1553, naming a Monday of the church year.[2][14] Tiktin also finds it in the Codicele Voronețean.[15] Coresi's book of homilies of 1581, MDA2's first record, has the Pharisee who fasts two days a week, „luni și joi” “Monday and Thursday”.[16][2]

Semantic evolution

The word has kept the single sense “Monday”; used without an article it means the coming Monday (plec luni), and articled, lunea, every Monday.[4][7] Folk calendars name particular Mondays: Lunea curată, the first day of Lent, Lunea păstorilor, a shepherds' holiday, and Lunea rătăcită, the Monday between Ascension and Pentecost.[15][16] The pious fasted on Mondays too, hence the ironic postește lunile “he has nothing to eat”.[15]

Names of cattle born on a Monday are formed from it: Banat Lunilă and Megleno-Romanian Lunce for an ox.[12][9]
