Forms

expertise f (countable and uncountable, plural expertises)[1] Middle French espertise (14th century) and expertice (1580, Montaigne); the modern spelling is found before 1614 in Brantôme.[2][3][4]

Etymology

It is formed from French expert + -ise, first as espertise, on espert, the older form of the adjective.[5][2][3][6] That adjective, meaning “skilful”, goes back to Latin expertus, the past participle of experior (“to try, test”);[7] The modern form of the adjective was remade after the Latin.[7]

Littré compares Occitan esperteza and Spanish esperteza.[8]

Earliest recorded meaning

In the 14th century espertise meant skill, dexterity or experience: Jean Le Fèvre uses it in his Vieille (before 1376).[5][9] An account book of the French royal household of 1381 speaks of joueurs d'espertise, performers of feats of skill.[9]

Semantic evolution

The general sense of skill or experience lasted until at least Cotgrave (1611):[5] Montaigne wrote of an expertise bellique, military experience.[8][3] The legal sense, an appraisal or report made by experts, appears in 1792,[5][7][4] and gave the verb expertiser (1807) and contre-expertise (1847).[4] It came to cover the valuation of objects such as works of art and the checking of their authenticity.[10]

Under the influence of English it took back the sense of an expert's knowledge and competence, which the Petit Robert notes fits the word's origin;[10] Rey notes that it serves as a French equivalent of English know-how.[4] English had itself borrowed expertise from French in 1868, at first for the quality of being an expert.[11]
