escalation

Etymology

It is formed from English escalate + -ation.^[2][3][4] Merriam-Webster derives it instead from escalator and -ion.^[5] The noun is recorded two decades before the verb came into general figurative use in 1959; the verb itself was a back-formation from escalator, first meaning "to ride an escalator" (1922).^[4][2] Escalator, the moving staircase, began in 1900 as a trade name of the Otis Elevator Company in the United States, coined from escalade after elevator;^[4][2][5] escalade, an assault on a fortified place with ladders, is from French escalade, from Italian scalata, from scalare (“to climb by a ladder”), from scala (“ladder”).^[4]

Earliest recorded meaning

The act or process of increasing armaments, prices or wages: 1938, in the Kansas City Star.^[2] Etymonline notes that this figurative use is the earliest, first applied to the race among the great powers to build battleships.^[4]

Semantic evolution

Merriam-Webster records an early technical sense: an increase, as in a price or in the tonnage of a nation's warships, that makes up for a discrepancy, such as between the price of a product and the cost of its materials, or between the fleets of nations bound by the same treaty; hence the regular adjustment of prices to changes in costs.^[5] The wider sense of an increase or development by successive stages, especially of a war or dispute, grew with the verb escalate, which came into general use in 1959 in scenarios of a possible nuclear war,^[4][3][2] and the transitive verb followed by 1962.^[4] The Oxford Dictionary of English now gives two senses: a rapid increase, as of costs, and an increase in the intensity or seriousness of something, such as violence.^[6]
