Forms

eroare f (plural erori)[1]

Etymology

It is borrowed from French erreur (“error”), with Latin error (“wandering; mistake”) as a second source, as MDA2, DEX 2009 and Wiktionary give it;[2][3][1][4][5][6] DELR, the DLR and Marcu and Maneca add Italian errore.[2][3][1][4][5][6] Ciorănescu gives Latin alone, a 19th-century borrowing of the accusative errōrem.[7]

The Latin word properly meant “wandering”; it is formed from errō (“to wander, to go astray, to be mistaken”) with the suffix -or.[4][1][8] The French word is a 12th-century borrowing of the same Latin word.[9]

Earliest recorded meaning

DELR dates the first record to 1846, in Laurian, with the sense “false idea or opinion; mistake”;[4][10] Tiktin also dates it to 1846.[4][10] MDA2's first record is Heliade's translation of Byron's Don Juan, of 1847.[2] The early texts also have the variants eroară, eroră and erore.[4] Zalomit wrote in this way that man „e capabil de veritate sau eroră” “is capable of truth or error”.[5]

Semantic evolution

From the start the word meant both a false belief and a single mistake; Șăineanu and Scriban give eroare de calcul “error of calculation”.[11][12][5] CADE adds the scientific sense, the difference between a calculated and an observed value, which the modern dictionaries define as the difference between the real and the calculated value of a quantity.[13][3] In law it is a false picture of the facts or of the law that can void an act;[3][2] eroare judiciară is a miscarriage of justice.[3][2] The phrase a induce (pe cineva) în eroare “to mislead” is quoted by the DLR from Eminescu and Caragiale on.[5]

DELR records the derivatives eronat “erroneous”, from French erroné, in 1856, the obsolete eroneu in 1860 and the back-formation erona “to falsify” in 1926.[4]
