单词 phlogiston
释义

phlogistonn.

Brit. /flə(ʊ)ˈdʒɪstɒn/, /flə(ʊ)ˈdʒɪstən/, U.S. /floʊˈdʒɪsˌtɑn/, /floʊˈdʒɪstən/
Origin: A borrowing from Latin. Etymon: Latin phlogiston.
Etymology: < post-classical Latin phlogiston (see quot. 1702) < ancient Greek ϕλογιστόν , neuter of ϕλογιστός burnt up, inflammable < ϕλογίζειν to set on fire ( < ϕλογ- , ϕλόξ flame (see phlox n.) + -ίζειν -ize suffix) + -τός, suffix forming verbal adjectives.The use of the term in sense 1 and the theory connected with it were introduced by Stahl in 1702, in his edition of Beccher's Physica Subterranea of 1669:1702 G. E. Stahl Spec. Beccherianum i. i. xvi. 19 in B.'s Phys. Subterr. (1732) Ad substantiam ipsam mixti, ut ingrediens..ut materiale principium, et pars totius compositi constitutiva, concurrit, materia et principium ignis, non ipse ignis: Ego Phlogiston appellare cœpi. The phrase ‘esse ϕλογιστὸν’ had been used by Sennert in the sense ‘the being flammable’, i.e. flammability or combustibility as a quality of some substances, but not regarded as a substance or principle:1619 D. Sennertus De Chym. Consensu ac Dissensu 283 At Colores, Odores, Sapores, esse ϕλογιστὸν & similia alia, mineralibus, metallis, gemmis lapidibus, plantis, animalibus insunt. The existence of phlogiston was denied by Lavoisier in 1775, and though stoutly maintained by Priestley, the belief in it was generally abandoned by 1800. N.E.D. (1906) also gives a partial pronunciation (-gi·stǫ̆n) /-ˈɡɪstən/.
1. Chemistry. A hypothetical substance formerly supposed to exist in combination in all combustible bodies, and to be released in the process of combustion (by some identified with the element fire, conceived as being fixed in flammable substances). Now historical.
