Etymology tree
Forms
inexcusable (plural inexcusables)[1] Recorded by the Académie in 1694 as an adjective of both genders.[2]
Etymology
It is borrowed from Latin inexcūsābilis (“that cannot be excused”), first recorded in 1402.[3][4][5] The Latin adjective is formed from in- (“not”) and excūsābilis (“excusable”), from excūsō (“to excuse, justify”), itself from ex- and causa (“cause”).[6][7] The FEW lists it under the Latin verb, the source of excuser.[8][9]
Earliest recorded meaning
The first record is in Jean Gerson's treatise against the Roman de la Rose (1402), where the worst charges are called les plus griefs et plus inexcusables, the most serious and least excusable.[9][3]
Semantic evolution
Gerson's first record applies it to charges that admit no excuse.[9] The GLLF dates its use of a person who has no excuse to 1474, in the Mystère de l'incarnation, and its use of a thing that cannot be excused to Montaigne (1588).[6] The Académie recorded it in 1694 with the example faute inexcusable.[2]
Rey notes that it is used rather more than the simple excusable, especially in the broad sense “morally without excuse”, like intolérable or inacceptable.[4] The adverb inexcusablement appeared in 1545 but is rare.[4][10]
