Etymology

Probably formed by the suffixation of the Latin vīcēsimus (“twentieth”) with the English -ation on the pattern of decimation, but compare the Latin vīcēsimātiō (“a killing of every twentieth man”); the spelling vigesimation is an alteration of vicesimation under the influence of vigesimal.
