Etymology
It is inherited from Latin cum (“with”).[2][3][4][5][1] The Latin preposition comes from Proto-Indo-European *ḱóm (“next to, at, with”).[1]
The preposition survives in all four branches: Aromanian cu, Megleno-Romanian cu and Istro-Romanian cu.[2][3][6] Its Romance cognates include Italian con, Spanish con and Portuguese com;[3][7][8] French kept it only in compounds.[3][7][8]
Earliest recorded meaning
DELR dates it to about 1500, in the Psaltirea Hurmuzaki, where it occurs over three hundred times.[2][9] Tiktin's first dated record is Neacșu's letter of 1521.[10]
Semantic evolution
From the Latin sense of company the preposition came to express the instrument, the content, possession and quality, the manner, the cause and the time of an action.[3][11] Ciorănescu compares its use in manner phrases such as cu drag “fondly” with the Romance adverbs in -mente.[3] In phrases like cu toate că “although” it builds conjunctions, and between two nouns it can mean “and”.[11]
Timeline
- c. 1500 – the first record, in the Psaltirea Hurmuzaki.[2][9]
- 1521 – in Neacșu's letter.[10]
- c. 1563 – the Codicele Voronețean.[5]
