“inexcusable” in Latin

The English word inexcusable itself goes back to Latin excūsō, through inexcusabilis.

Riddle & Arnold A Copious and Critical English–Latin Lexicon, 1864

inexcusable
quod nihil excusationis habet (e.g., vitium): cui venia nulla proponitur (e.g., erratum, Cic.): cui ignoscendum non est; cui ignosci non or nullo modo potest: inexpiabilis (for which no atonement can be made): qui nulla excusatione se defendere potest (of persons): cui nulla satis justa excusatio est. To be inexcusable, nihil excusationis habere; excusationem non habere; cui nulla venia proponitur (all of things). Anybody was less inexcusable, magis alicui ignoscendum fuit (Cic.). Every citizen who did not attend was held to be inexcusable, nemini civi ulla, quominus adesset, satis justa excusatio visa est (Cic.): ☞ inexcusabilis poetical (Hor., Ov.), and late (Dig.).
