Forms

différenciation f (plural différenciations)[1]

Etymology

It is formed from French différencier + -ation, on the stem of the verb.[2][3][4] The verb was taken from scholastic from Medieval Latin differentiō (“to differentiate”) (about 1360), which is from differentia (“difference”).[2][4] The spelling différentiation (1829, Boiste) is formed in the same way from différentier, the variant of the verb used in mathematics.[2][4]

Earliest recorded meaning

Cuvier used it in 1808 for the acquiring of distinctive characters, a transformation.[2][3][5]

Semantic evolution

The sense “action of differentiating, of distinguishing” is recorded in Pierre Leroux in 1840.[2] The GLLF instead dates the general sense to the Académie in 1827 and the sense of acquiring distinctive characters to Larousse in 1888.[6][7] In biology it became the process by which a cell or tissue acquires its specific characters, and différentiation was used in mathematics from 1839.[4][2] Economics, phonetics and sociology later gave it technical senses of their own.[2]

On its stem were formed différenciateur (1916, Saussure) and différenciatif (about 1953); indifférenciation is found in Proudhon in 1843, and biology formed dédifférenciation for cells that lose their characters.[4]
