Etymology tree
Forms
indomitābilis (neuter indomitābile); third-declension two-termination adjective[1]
Etymology
It is formed from Latin in-2 (“not”) + domitō (“to tame”) + -bilis,[2][3] through an unattested *domitābilis, according to Etymonline, which takes domitō as the frequentative of domō (“to tame”).[3] Lewis & Short and Jeanneau relate it instead to indomitus “untamed”.[1][4]
Earliest recorded meaning
Its only ancient record is in chapter 30 of a treatise on penance, which Lewis & Short attribute to Victor of Tunnuna and Gaffiot to Ambrose;[1][5] Köbler lists it under Pseudo-Ambrose and dates it, with a query, to the 6th century AD.[2] There it means “that cannot be subdued”.[1][5]
Semantic evolution
It belonged to Ecclesiastical Latin.[1][6] In the Latin of medieval and early modern Hungary it described what cannot be checked or conquered, as a warlike people.[7] The DMLBS files it under the older indomabilis.[8]
English took it over in the 1630s as indomitable, “that cannot be tamed”; the sense “unyielding, resolute” of people is from about 1830.[3]
Timeline
- 6th century AD (?) – A treatise on penance ascribed to Ambrose uses it.[2][1]
