英語の語源
inexorable
inexorable: [16] Etymologically, inexorable means ‘that cannot be removed by praying’. It is an adjective of many layers, of which the original is Latin ōrāre ‘pray’ (source of English oracle, orator, etc). Addition of the prefix ex- ‘out’ produced exōrāre ‘remove by pleading or entreating’, and further prefixation and suffixation gave inexōrābilis, which entered English partly via French inexorable. => oracle, orator
inexorable (adj.)
1550s, from Middle French inexorable and directly from Latin inexorabilis "that cannot be moved by entreaty," from in- "not, opposite of" (see in- (1)) + exorabilis "able to be entreated," from exorare "to prevail upon," from ex- "out" (see ex-) + orare "pray" (see orator). Related: Inexorably; inexorability.
