Forms
frauduleux (feminine frauduleuse, masculine plural frauduleux, feminine plural frauduleuses)[1] Middle French also had fraudeleux (15th century).[2]
Etymology
It is borrowed from Late Latin fraudulōsus (“fraudulent”), a Late Latin legal word,[3][4][1] from fraus (“fraud”).[2][5] Bloch and Wartburg note that it was borrowed to serve as the adjective of fraude.[6]
Earliest recorded meaning
The first record is in Nicole Oresme's treatise on money, where exaction frauduleuse is a levy tainted by fraud; the TLFi dates the passage to 1365, while the Robert dictionaries, the GLLF and Rey give about 1361.[3][5][4][7] Littré quotes marchiés frauduleux “fraudulent dealings” from Oresme.[2]
Semantic evolution
From the start the adjective described acts and things tainted by fraud.[3][7] About 1560 Ambroise Paré applied it to people, “given to fraud, deceitful”, a use the TLFi and GLLF now call old or classical.[4][2][3] By 1764 Voltaire used it of things in the sense “false, falsified”, also now dated.[4][8]
In law, banqueroute frauduleuse (1675) is a bankruptcy in which the debtor has hidden or diverted assets, and a banqueroutier frauduleux is one guilty of it.[4][8][2] Littré also gives the sense “evading customs or excise duties”.[2] The adverb frauduleusement followed about 1398.[7]
