Definition of phlogiston in English: phlogistonnoun fləˈɡɪst(ə)nfləˈdʒɪst(ə)nfloʊˈdʒɪstən mass nounA substance supposed by 18th-century chemists to exist in all combustible bodies, and to be released in combustion. （18世纪化学家认为存在于所有可燃物中且燃烧时会释放的）燃素 Example sentencesExamples - And combustion, as they understood it, happened when phlogiston, a hypothetical earthlike substance characterized mainly by its combustibility, was removed from an object.
- For example, sun-centered astronomy replaced earth-centered, oxygen superseded phlogiston, and absolute space gave way to curved space.
- According to the phlogiston theory, combustible materials contain a substance - phlogiston - that is emitted by the material as it burns.
- In the phlogiston theory, phlogiston is released during combustion, and in the oxygen theory, oxygen is absorbed during combustion.
- Biologists used to believe in the inheritance of acquired characteristics, chemists in phlogiston, physicists in absolute (pre-relativity) time.
OriginMid 18th century: modern Latin, from Greek phlogizein 'set on fire', from phlox, phlog- 'flame', from the base of phlegein 'to burn'.
