proliferation

Etymology

It is borrowed from French prolifération,^{[2][3][4][5][6][7]} from prolifère (“producing offspring, proliferous”),^[2][3][5] from Latin prōlēs (“offspring”) and -fer (“bearing”), from ferō (“to bear, carry”),^[2][3] from Proto-Indo-European *bher- (“to carry; to bear children”).^[2] Merriam-Webster derives the French noun from proliférer (“to proliferate”).^[7] The OED, revising the entry in 2007, takes it instead as an English formation from New Latin prolifer (“proliferous”), used in botany from 1581, and the suffix -ation, with a first record in 1759.^[8] It is related to prolific and proletarian.^[2][3]

Earliest recorded meaning

In botany, the condition of having extra buds, flowers or shoots growing where they are not usual: 1759, in John Hill's Vegetable System.^[8] The other dictionaries begin with the 19th-century biological sense, the formation of cells by budding or division: Etymonline in 1859, Barnhart in 1867.^[2][3]

Semantic evolution

In biology and medicine the word meant the growth of tissue by cell division or budding (1864), and in zoology the production of sexual zooids by hydrozoans, recorded in the Century Dictionary of 1890.^[8][4] The general sense of rapid increase in number or extent is found from 1904,^[8] from 1920 according to Etymonline.^[2] From about 1960 it was used especially of the spread of nuclear weapons, first in the jargon of the United States State Department;^[2] the Shorter Oxford calls this now the main use.^[4] The verb proliferate is a back-formation from the noun,^[3][2] recorded from 1866 in the OED,^[8] and took the general sense "increase rapidly in number" in 1915.^[8]
