alkaligenn.

Brit.

/ˈalkəlᵻdʒ(ə)n/, U.S.

/ˈælkəˌlidʒ(ə)n/

Forms: 1700s– alkaligen, 1700s– alkaligene.

Origin: Formed within English, by compounding; modelled on a French lexical item. Etymons: alkali n., -gen comb. form.

Etymology: < alkali n. + -gen comb. form, after French alcaligène (1787 in Fourcroy as noun (compare quot. 1788); also as adjective: see alkaligenous adj.). Compare slightly later alkaligenous adj.

Chemistry. Now historical.

Originally: (A. F. de Fourcroy's name for) nitrogen. Later: a supposed essential component of alkalis.

1788 J. St. John tr. L. B. Guyton de Morveau et al. Method Chym. Nomencl. 26 It appears to deserve the appellation of alkaligen, as was proposed by Mr. de Fourcroy.

1798 Crit. Rev. 23 435 Dr. Dickson..gives judicious reasons for not adopting azote, nitrogene, or alkaligene.

1806 Philadelphia Med. Mus. 2 58 The other substance entering into the composition of hydrogene, is what I shall denominate alkaligene or the base of alkalies of every kind.

1855 Chemist 3 460 The knowledge and sagacity of Davy induced that distinguished man to seek for an alkaligen (or generator of alkali) at that..pole of the voltaic battery, where Nicholson and Carlisle had recently found hydrogen (generator of water). This alkaligen was the metal of the alkali.

1992 D. Knight Humphry Davy (1998) v. 66 In the notebook he remarked of the alkaligen, ‘the substance is analogous to those..imagined to exist by the..alchemical visionaries.’
