indisputable

Etymology

It is borrowed from Late Latin indisputābilis,^{[2][3][4][5][6][7]} found in Cassiodorus,^[2] from Latin in- (“not”) and disputābilis (“disputable”),^[2][5][6] from disputō (“to weigh, examine, discuss, argue”),^[3] which is formed from dis- (“apart”) and putō (“to count, consider”), from Proto-Indo-European *pau- (“to cut, strike”).^[3] Johnson derived it simply from disputable with a negative prefix.^[8]

Earliest recorded meaning

That cannot be disputed; unquestionable: 1551, in R. Robinson's translation of More's Utopia.^[2][6] Etymonline gives the 1550s and Dictionary.com 1545–55.^[3][9]

Semantic evolution

The meaning has hardly changed since it was first recorded.^[2][10] Johnson (1755) defined it as “uncontrovertible; incontestable”, quoting Addison's “no maxim in politicks more indisputable”,^[8] and his 1773 edition added “evident; certain”.^[8] Merriam-Webster also records a weakened use, truly existing or real beyond doubt.^[6] A single use in Richardson's Pamela (1741) for “undisputing” did not last.^[2]
