Forms

indomābilis (neuter indomābile); third-declension two-termination adjective[1][2]

Etymology

It is formed from Latin in- (“not”) + domābilis (“tameable”).[1][3][4] The base comes from domō (“to tame”), which de Vaan traces to Proto-Italic *domaje- and Proto-Indo-European *domh₂-eie/o- (“to tame”).[5]

Earliest recorded meaning

Plautus (c. 250–184 BC)[4] has it in the Casina: edepol ne tu, si equos esses, esses indomabilis, “by Pollux, if you were a horse, you would be untameable”.[3][2]

Semantic evolution

The word stayed rare in Classical Latin.[3][2] Late writers apply it to animals (the bulls of Colchis in the Vatican Mythographers, the fox in Jerome, a calf in the fables of Romulus),[3] and then to people: Porphyrio's commentary on Horace, Prudentius praising the steadfastness of a Christian martyr, and the Vulgate's sons “of hard face and stubborn heart” (indomabili corde, Ezekiel 2:4).[3] Cassiodorus compares the flesh to an untameable beast.[3] Köbler finds it also in medieval charters, in Notker's Gesta Karoli and in Widukind.[4]
