Forms

ultimatum m (plural ultimatums or ultimata)[1]

Etymology

It is borrowed from Medieval Latin ultimatum, a word of diplomatic usage derived from Latin ultimus (“last”) on the model of imperātum (“command”).[2][3][4] Rey and the Grand Robert give the Medieval Latin source as ultimatus, which Du Cange notes was used in the neuter in the German chancelleries of the 15th century, in a phrase meaning “final decision”.[5][6] Littré explained it as the passive participle of a Latin verb meaning “to come to the end”, formed from the same adjective.[7]

Earliest recorded meaning

It is first recorded in 1740, in the Journal of the Marquis d'Argenson, meaning “final word, irrevocable decision”.[2][5]

Semantic evolution

From the end of the 18th century the word came to mean a demand declared irrevocable, which must be met within a set time,[2][5] and in the 19th century it was used especially between states, as the last conditions whose refusal leads to a break in relations and usually to war.[5][2] The broader sense of any firm, final resolution, as of a general or a businessman, is recorded by Littré.[7] The variant ultimat (1803) has gone out of use; the rare literary adjective ultimatif dates from 1923.[5]

Timeline

  • 1740 – D'Argenson uses it for an irrevocable decision.[2][3]
