Forms
zău[1] Old texts also write dzău: „Eu, dzău, numai doi cai am avut acum” “I, by God, had only two horses then” (a document of 1657).[2] In Maramureș the form is dzău, in Lăpuș zo.[3] In the 19th century the word was often written zeu, like the noun.[4]
Etymology
It is inherited from Latin deus (“god”), used in oaths as “by God”.[5][4][6][1] Ciorănescu calls it a doublet of zeu “god”, which also comes from the Latin word.[5] The Academy dictionaries are more cautious: MDA2 marks the origin as unknown and compares zeu, and the DLR only compares it.[7][2] Wiktionary gives both explanations: the Latin word itself, or a variant of that noun which kept the oath use.[1] Tiktin takes the interjection as a whole oath cut down to its first word, and compares German Gott ist mein Zeuge (“God is my witness”).[4] For Maramureș, Ștef connects the local form with the oath „jur pe Dum'nedzău” “I swear by God”, and the form of Lăpuș with the regional name of God.[3]
Aromanian keeps the word only in the phrase niți dzău (“not a word”).[5][8] Its Romance cognates include Italian dio, Portuguese deus, French dieu, Catalan déu and Spanish dios.[5][9] The Latin noun comes from Old Latin deivos and Proto-Indo-European *deywós, a derivative of *dyew- (“sky, heaven”).[1][10]
Earliest recorded meaning
Tiktin dates the first record to 1563, in Coresi's Praxiu.[4] MDA2 and the DLR begin with the Palia de la Orăștie of 1581, where the word already strengthens a reproach: „N-ai neci lăsat să sărut feciorii și featele meale, dzău, nebuneaște ai făcut” “you did not even let me kiss my sons and my daughters; truly, you have acted foolishly”.[2][7]
Semantic evolution
From the start the word backs up a statement, much like “truly”.[2] A manuscript of the early 17th century renders the Gospel formula “verily I say unto you” with it: „Zău zic voo că cine va creade în mine și în cuvintele meale, nu va muri în veaci” “truly I tell you that whoever believes in me and in my words will never die”.[2][4]
In folk poetry a zice zău means “to swear”.[4][6] Formulas such as nu știu, zău came to express doubt or wonder, and with a request the word means “please”.[7][6] Modern dictionaries label it popular.[7][11]
