Forms

indisputābilis (neuter indisputābile); third-declension two-termination adjective[1][2]

Etymology

It is from Latin in-2 + disputābilis.[3][4] Etymonline traces the base to disputō (“to discuss, argue”).[5]

Earliest recorded meaning

Maximus of Turin (395–415 AD) has it first, in a homily, of the divinity of Christ that is beyond dispute.[3][2][4]

Semantic evolution

Cassiodorus uses it of an unquestionable testimony.[1][3][6] Niermeyer gives the medieval sense incontestable,[7] and the DMLBS records it in Thomas More's Utopia of a prerogative of the prince that cannot be challenged.[8]

English indisputable (1550s) comes from it.[5]
