Word History

Etymology

borrowed from French taxonomie, from Greek táxis "arrangement, order" + French -o- -o- + -nomie -nomy — more at taxis

Note: French taxonomie was a coinage of the Geneva-born botanist Augustin Pyramus de Candolle (1778-1841), in Théorie élémentaire de la botanique (Paris, 1813). Candolle divided botany into three divisions (p. 19): "… elle se compose 1.^o de la Glossologie, c'est-à-dire, de la connaissance des termes par lesquels on designe les organes des plantes et leurs diverses modification; 2.^o de la Taxonomie [footnote: "Mot formé de ταξις ordre, et νόμος loi, règle."], ou de la Théorie des classifications appliquée au règne végétal; 3.^o de la Phytographie, ou de l'art de décrire les plantes de la manière la plus utile aux progrès de la science …" ("… it is composed of 1.^o Glossology, that is, the recognition of the terms by which the organs of plants are designated, and their various modifications; ; 2.^o Taxonomy [footnote: "Word formed from táxis order, and nómos law, rule."], or the theory of classifications applied to the vegetable kingdom; 3.^o Phytography, or the art of describing plants in the manner most suited to the progress of science"). A more correct compounding form in terms of Greek word formation would have been taxi- (as táxis is an i-stem), and taxinomy did in fact see some use in the 19th century—though Candolle's original coinage has predominated. His parallel introductions, glossology and phytography, have rarely been employed.
