Forms

fiduciaire (plural fiduciaires)[1]

Etymology

It is borrowed from Latin fīdūciārius (“entrusted as a deposit, provisional”), which in Late Latin became a legal term.[2][3][4] The Latin adjective is derived from fīdūcia (“trust, confidence”) and, in its legal use, from fīdus (“trustworthy”), itself from fīdō (“to trust”).[3][5] Littré traces the family further to fidēs (“faith”), the source of foi.[5]

The English word fiduciary was taken directly from the Latin adjective in the 1640s.[6]

Earliest recorded meaning

The TLFi's first record is from 1593, in a legal text on the practice of Mesver (cited by Huguet from a 1603 edition), where nécessité fiduciaire means an obligation resting on a clause of trust.[2] The Grand Robert, the GLLF and the Petit Robert date the word from Hulsius's dictionary of 1596.[7][8][9]

Semantic evolution

At first a term of law, fiduciaire qualified whatever had to do with the fiducie, the transfer of property in trust; the phrase héritier fiduciaire, an heir charged with handing a bequest on to another, is recorded in 1596 and still survives.[3][2] The Petit Robert dates the adverb fiduciairement to 1839.[9]

In the 19th century political economy applied the word to values that rest only on the confidence placed in whoever issues them: Littré records monnaie fiduciaire “paper money” in 1865, and circulation fiduciaire is found by 1890.[2][3][8] Valéry extended it, before 1945, to anything founded on trust or convention.[8] In modern use une fiduciaire (for société fiduciaire) is a firm that handles the accounts and administration of other companies,[9][10] and in Switzerland the noun also names an intermediary acting in trust for clients.[11]
