Pronunciation

Etymology

The word for “as, like” is inherited from Latin quam (“how, as, than”).[2][3][4][5][6] It survives in all four branches as Aromanian ca, Megleno-Romanian ca and Istro-Romanian ca,[2][3] and in Old Italian, Sardinian, Old Spanish and Old Portuguese ⟨ca⟩;[3] Spanish cuan and Portuguese quão are cognates too.[2]

Ciorănescu identifies it with cam “about”: ⟨ca⟩ once had that sense too, and the two forms separated only fairly recently.[2] The compounds ⟨ca și⟩, ⟨ca și cum⟩ and ⟨ca și când⟩ seem to be Romanian formations, but Philippide and Pascu derive ⟨ca și⟩ from Latin quasi (“as if”).[2][1]

Earliest recorded meaning

DELR dates the word to about 1500, and it is frequent in the Hurmuzaki Psalter of the early 16th century.[3][7] Tiktin's first record is Neacșu's letter of 1521.[8] The first sense is the comparison “as, like”.[3]

Semantic evolution

Besides comparison, the old language used it as a conjunction of manner, time and condition, “how, when, if”, and as “about”.[3][9] The sense “about, approximately” passed to cam, and ca keeps it only in phrases like ca la cinci metri.[2][10] As a preposition it governs the accusative, ca mine.[2]

In Muntenia, often after ci, it is used with an imperative to urge someone on, ca dă-te mai încoace;[11][4] DELR takes this as a separate word of uncertain origin, probably the same ca “about”.[11][4]

Pronunciation

Etymology

The word for “(so) that” is inherited from Latin quia (“because”) according to Ciorănescu, Pușcariu, the DA, MDA2 and DEX.[2][5][12][10][4][1] Latin ⟨quia⟩ also gave Old Italian, southern Italian, Old Spanish and Old Portuguese ⟨ca⟩, and Italian che;[2] Ciorănescu notes that the REW does not list the Romanian, Aromanian and Megleno-Romanian forms.[2]

DELR rejects this: the quia hypothesis does not explain why the conjunction occurs only with the subjunctive.[13] With Tiktin and the REW it takes the word as ca1 from quam, its sense of purpose grown out of “how, as”, as with ut, Ancient Greek ὡς (hōs) and Old Romanian ⟨cum să⟩, which meant ⟨ca să⟩.[13] The conjunction exists in Aromanian, Megleno- and Istro-Romanian too.[13]

Earliest recorded meaning

DELR dates the conjunction to about 1500.[13] MDA2's first record is the Cuvente den bătrâni collection, before 1577.[10] In the oldest texts final clauses were introduced by cum să rather than ca să.[12]

Semantic evolution

The old sense “because, since” was lost in the 17th century, and the word survives only before să, introducing the subjunctive of purpose or result: plec, ca să nu-l mai aud.[2] It is needed when words come between the main verb and the subjunctive, vreau ca fratele meu să vină.[2] From such sentences ca să has spread where să alone would do.[2]

Timeline

  • c. 1500 – first recorded.[13]
  • before 1577 – in the Cuvente den bătrâni collection.[10]
  • 17th century – the sense “because” falls out of use.[2]

Meanings

Conjunction

  1. (obsolete) because, since.[2][1]
  2. (followed by să) In order that, so that: A venit ca să ne ajute.[4][2][1]
  3. (followed by să after other words) that, introducing a subjunctive clause: Vreau ca toți să fie de față.[4][10]

Usage notes

Ciorănescu considers ca să where plain să follows the verb (nu vreau ca să plece) improper, though it is less and less felt as such.[2]
