Forms
confidentiel (feminine confidentielle, masculine plural confidentiels, feminine plural confidentielles)[1]
Etymology
It is formed from French confidence + -iel.[2][3][4][5] Wiktionary instead derives it from confident with the same suffix.[1] The base noun is from Latin cōnfīdentia.[5]
In form it recalls Medieval Latin confidentialis (“bold, self-assured”), recorded about 1318, but the French word was made on the French noun.[2][4]
Earliest recorded meaning
It is first recorded in 1775, in a letter of the minister Vergennes to Ossun, of something told in confidence.[2][6]
Semantic evolution
Unlike confidence and confident, which stayed literary words about private feelings, confidentiel became an administrative term, a milder equivalent of secret.[4] An official note marked confidentiel is one passed only to certain officials.[6]
From the sense “kept to a few people” it came to describe whatever reaches only a small circle, such as a review or a work with few readers.[2][7] The adverb confidentiellement is as old as the adjective (1775), and the noun confidentialité (1970) is a calque of English confidentiality.[4]
