Pronunciation

Forms

deci (conjunction, invariable)[2] The 16th-century texts write deaci: „Deaci preveghiați” “therefore watch” (Codicele Voronețean, Acts 20:31).[3][4] DELR also lists the old variants dăci, deace, dece and dici.[4]

Etymology

It is formed from Romanian de (“from”) + aci (“here”), literally “from here, hence”; the older form was deaci.[4][2][5][1] Tiktin also takes it as probably so formed, at first with the same meaning as deacii “thereupon”.[3] Scriban explained it from de and ici.[6] Wiktionary compares French d'ici.[1]

aci “here” continues Latin eccum and hīc (“here”).[7] Cihac's derivation from dē and quid is not followed.[8][4]

Earliest recorded meaning

DELR's first record is deaci in the Codex Bratul of 1559–1560.[4] In the Codicele Voronețean (c. 1563–1583) it renders Greek “therefore” in „Deaci preveghiați” and Greek “and then” in „Deaci se aproprie miiașul” “then the captain came near”.[3][5]

Semantic evolution

The old sense “then, after that”, used to move a story on, is now obsolete.[4][3] The conclusive sense, “so, therefore”, became the main one, and the conjunction still resumes an interrupted story: Deci, cum spuneam…[5][2] Scriban illustrates it with Descartes' cuget, deci exist “I think, therefore I am”.[6] The Bucharest Bible of 1688 already uses deci over four hundred times.[9]

Timeline

  • 1559–1560 – deaci in the Codex Bratul, the first record.[4]
  • c. 1563–1583 – deaci “therefore; then” in the Codicele Voronețean.[3][5]
  • 1649 – deci in Mardarie's Slavonic–Romanian lexicon.[10]
  • 1688 – deci over four hundred times in the Bucharest Bible.[9]

Meanings

Conjunction

  1. so, therefore, consequently: introduces a logical conclusion or a consequence: Am întârziat, deci am pierdut trenul.[2][5]
  2. so, well then: resumes a story after an interruption.[5]
  3. (obsolete) then, after that.[4]

Usage notes

A separate element deci-, from French déci-, forms the names of units one tenth of the main unit (decilitru, decimetru); MDA2 records it from DEX 1975.[2][5][11]
