Pronunciation

Forms

lună f (plural luni)[1] The Psaltirea Hurmuzaki writes the word with /r/ for /n/, lunra, in nine passages, among them Psalm 8:4.[2][3] Old texts also have the plural lune.[4]

Etymology

It is inherited from Latin lūna (“moon”).[5][4][1][6] The DÉRom counts it among the words inherited from Proto-Romance.[3] The Latin word is Old Latin losna, from Proto-Italic *louksnā, from Proto-Indo-European *lówksneh₂, a derivative of *lewk- (“light, bright”); it is related to lūx and lūmen.[1][7] The sense “month” already existed in popular Latin, as inscriptions show.[5]

The word survives in all four branches of Romanian: Aromanian lunã, Megleno-Romanian lună and Istro-Romanian lurę.[5][8][9] Its Romance cognates include Italian luna, Spanish luna, Occitan luna, French lune, Catalan lluna and Portuguese lua.[5][6]

Earliest recorded meaning

The oldest form is lunra in the Psaltirea Hurmuzaki of the early 16th century, in the psalm verse on the moon and the stars (Psalm 8:4).[2][3] MDA2's first record is the Cuvente den bătrâni collection of about 1550, and Tiktin gives 1567.[4][10] Coresi's psalter of 1570 has lună.[11]

Semantic evolution

The word names both the moon and the month, as in Latin.[5][1] Ciorănescu compares the Romanian phrase lună de miere “honeymoon” with French lune de miel;[5] Ciorănescu also records the sense “menstruation”.[5] Phrases describe the moon's phases: lună nouă “new moon”, lună plină “full moon” and, in folk speech, lună veche “waning moon”.[12][10]

Idioms use the moon for what is out of reach or unreal: a promite luna de pe cer “to promise the moon”, a fi căzut din lună “to be out of touch with reality”, câte-n lună și-n stele “every possible thing”.[12][10] As an adverb, lună means “spotless, gleaming”: o bucătărie curată lună “a spotless kitchen”.[10][12] Derivatives include lunar, after Latin lūnāris, and lunatic, from Latin lūnāticus.[5]
