proliférer[1]

Etymology

It is formed from French prolifère + -er.[2][3][4][5] That adjective (1766) was coined from prōlēs (“offspring”) on the model of adjectives such as frūgifer (“fruit-bearing”), with the ending -fère from ferō (“to bear”).[5][1]

Earliest recorded meaning

It is first recorded in the dictionary of Mozin and Peschier (1859), meaning “to multiply by reproducing”;[2][4] Rey thinks it is probably older.[6]

Semantic evolution

At first a learned word of biology, it was used in medicine by Claude Bernard (1878).[2][6] The sense “to produce beings like oneself” is recorded in 1890.[2]

Proust used it figuratively in 1922 for “to abound, to increase in number”, and through this sense it passed into common use.[2][6][4] The noun prolifération, from botany (1842) and biology (1869), followed the same path.[6] Non-prolifération (1966) was formed from it for the limitation of nuclear weapons.[6] English proliferation was taken from the French noun in 1859.[7]
