Pronunciation

  • /kət͡ʃʲ/[1]

Etymology

It is a compound from Romanian că + ce.[2][3][4][5][1] The DA explains it from questions joined to a verb of asking with că: the ce that introduced such a question often meant “why”, and that sense passed to the compound.[6] Ciorănescu likewise takes the old sense “why” to be closer to the original meaning of the compound.[3] The final ⟨e⟩ became ⟨i⟩ as in cinci and atunci.[6]

Pușcariu and Șăineanu derived it from Latin quod + quid, the sources of its two parts.[7][8] It survives south of the Danube: Aromanian cãtse “why; because” and Megleno-Romanian kǫți.[9][3] Ciorănescu notes a Wallachian pronunciation with ⟨î⟩, the source in his view of a Bulgarian word meaning “as if”.[3]

Earliest recorded meaning

DELR dates the conjunction to 1551;[2][10] Tiktin's first record is in a Gospel text of 1551–1553, at Matthew 5:34.[2][10] MDA2's first record is in Gaster's chrestomathy, dated 1550.[4] In Coresi and the other old texts the form căce often means “why?”: Căce ei se botează pre morți? “why are they baptized for the dead?”.[6]

Semantic evolution

Old Romanian used the word as an adverb “why?” and as a conjunction “because”, and also for “that” after verbs of saying and accusing: Dosoftei writes that the martyrs were accused căce sunt creștini “of being Christians”.[10][6] Compound forms pentru căci and căci că were common in the 17th and 18th centuries.[10][11] The interrogative sense survives only in exclamations of regret, as in Alecsandri's Căci n-am durdă…! “If only I had a gun!”.[10][12] Today it is a literary conjunction introducing explanatory clauses, “for, because”, while speech prefers că.[5][1][11]

Timeline

  • 1551 – the first record, in a Gospel text (Matthew 5:34).[2][10]
  • 1570 – căce in Coresi's psalter.[13]
  • mid-17th century – căce becomes căci.[6]
  • 1688 – căci in the Bucharest Bible, as in căci ai făcut aceasta? “why have you done this?” (Genesis 3:14).[14][6]
  • 1801 – Klein's dictionary glosses caci “why? for what reason?”.[15]

Meanings

Conjunction

  1. for, because: introduces an explanatory or causal clause;[5][4][1] Pleacă devreme, căci drumul e lung. “Leave early, for the road is long.”[5][4][1]
  2. (regional, archaic) Why? In exclamations: why ever, if only.[2][12]

Usage notes

The word is literary; in speech the same clauses are usually joined with că, fiindcă or pentru că.[1][11] The old form was căce, at first stressed on the last syllable, as in Coresi's psalter of 1570; the DA dates the change to căci to about the middle of the 17th century.[13][6] Other old variants are câce and căi.[4][2]
