mobilize

Etymology

It is borrowed from French mobiliser,^{[2][3][4][5][6][7][8]} formed from mobile (“movable”) with the suffix -iser, the French counterpart of -ize.^[6][9][5] In French the verb is recorded from 1765 in law, for declaring property movable, in finance by 1797, and since 1834 for making troops ready for war.^[2] The French adjective comes from Latin mōbilis (“movable, easy to move”), a contraction of *movibilis, from moveō (“to move”).^[3] Dictionary.com instead takes the English verb as a back-formation from mobilization.^[10]

Earliest recorded meaning

To make a person or group active or capable of action: 1838, in the Globe of 15 January.^[2] Barnhart's first record, also from 1838, has the sense "to put into circulation",^[4][5] and Merriam-Webster too dates the word to 1838.^[6] Etymonline dates the military sense to 1833, "render capable of movement" to 1838 and "bring into readiness or circulation" to 1846.^[3]

Semantic evolution

The OED and Barnhart date the military sense, to prepare an army for war or call troops into active service, to 1853, in C. L. Brace's Home Life in Germany,^[2][4][5] and the intransitive use, of a country or army getting ready for war, to 1873.^[2] In finance the verb meant from 1864 to make capital or assets available,^[2] following the French economic use.^[2] From 1871 it was used figuratively of gathering and organizing resources, energy or support for a purpose,^[2][5] a sense that is now as common as the military one.^[11][6] Later technical senses are medical (1894: to restore movement to a joint, or to free an organ in surgery), physiological (1899: to release a substance or cells into use) and molecular biological (from 1965).^[2][8]

Usage notes

The British spelling is also mobilise.^[11][6] A slang mobilize, to beat someone up, recorded from 1923 in Samuel Ornitz's Haunch, Paunch and Jowl and used especially among Jews in New York, has a separate source: the OED suggests a Yiddish phrase meaning "to abort", with the suffix -ize, perhaps influenced by the ordinary verb.^[2][12]
