Pronunciation

Forms

zi f (plural zile)[1] Old texts write dzuo and zio: „Şi deca fu dzuo” “and when it was day” in the Codicele Voronețean, and „Până iaste zio să lucrăm” “let us work while it is day” in Coresi.[2] Beside zi there is ziuă, taken from the articled form ziua.[3][4]

Etymology

It is inherited from Latin diēs (“day”).[3][4][5][6][1] Wiktionary suggests that the articled ⟨ziua⟩ may continue Vulgar Latin *dilla, the indefinite form being shortened.[1] The Latin noun was formed from the accusative ⟨diem⟩ and goes back to Proto-Indo-European *dyḗws (“heaven, sky”).[1]

The word survives in all four branches: Aromanian dzuã, Megleno-Romanian zuuă and Istro-Romanian zi.[3][1][7][8] The Romance cognates include Dalmatian dai, Italian dì, Catalan dia, Spanish día and Portuguese dia.[3][6]

Earliest recorded meaning

The earliest record is dzuo in the Psaltirea Hurmuzaki of the early 16th century, in Psalm 120:6.[9] MDA2 and the DLR cite the Codicele Voronețean (c. 1563–1583): „Şi deca fu dzuo” “and when it was day”.[4][2]

Semantic evolution

The DLR and MDA2 begin with “daylight”, then “the time between sunrise and sunset”;[2][4][3] DER adds “date, term”, “feast day or name day” and, in the plural, “time, epoch” and “life”.[2][4][3] The sense “life” lies behind the derivative zili “to grant long life”.[3] The doublet ziuă is kept mostly in phrases such as se face ziuă “day breaks” and de cu ziuă “before dawn”.[3]

The word appears in the compounds astăzi, azi and deunăzi.[5][3] The neologism ziar “newspaper” was formed after Latin diārium.[3]
