Pronunciation

  • /proˈba.bil/[1]

Forms

probabil m or n (feminine singular probabilă, masculine plural probabili, feminine/neuter plural probabile)[1] An old form probabile occurs in the press of the 1850s: „carea din zi în zi se face tot mai probabile” “which becomes more probable day by day” (Telegraful, 1854).[2][3]

Etymology

It is borrowed from Latin probābilis (“worthy of approval; credible”), partly borrowed from French probable, with Italian probabile as a further model: MDA2 and the DLR give all three, DEX the French and Latin words, and Tiktin New Latin and Italian.[3][2][4][5] Negulici in 1848 gave only the Latin word, and the neologism dictionaries vary in which source they put first.[6][7][8]

The Latin adjective is formed from probō (“to test; to approve”) with -bilis.[9][1] French and Italian took it from Latin in the Middle Ages.[10][11]

Earliest recorded meaning

Tiktin's first record is from 1781, in a work of Micu, with the senses “possible” and, as an adverb, “possibly, probably”.[5] MDA2 dates it from Brezoianu's agricultural handbook of 1850, where it means “that may happen”: without prudence and steadfastness no success in farming is probable.[3][2]

Semantic evolution

Negulici's dictionary of neologisms (1848) defines it as “seeming to be true”, and Damé still marks it as a neologism in the 1890s.[6][12] Besides “likely to happen” it means “plausible”, and the adverbial use “probably, very likely” is now the most frequent.[4][13] Timpul probabil is the weather forecast for the coming days.[4]

Timeline

  • 1781 – the first record, in Micu.[5]
  • 1848 – Negulici's dictionary of neologisms, with Latin probabilis.[6]
  • 1850 – “that may happen”, in Brezoianu's agricultural handbook.[3][2]
  • 1854 – the form probabile in the newspaper Telegraful.[2]
  • 1870 – Costinescu glosses it “having the appearance of truth”.[14]
