英文詞源
- pyrotechnic
- pyrotechnic: [18] The Greek word for ‘fire’ was pūr (it came from the same prehistoric Indo- European source as English fire). It underlies a range of English words, including pyracantha [17] (etymologically ‘fire-thorn’), pyre [17], pyrethrum [16], and pyrites [16]. Pyrotechnic itself was derived from an earlier pyrotechny, which was originally used for the ‘manufacture of gunpowder, firearms, bombs, etc’. The application to ‘fireworks’ did not emerge until the 17th century.
=> fire, pyre, pyrites - pyrotechnic (adj.)
- 1704, "of or pertaining to fire;" 1825, "of or pertaining to fireworks," from pyro- + Greek tekhnikos "made by art," from tekhne "art" (see techno-). Figurative use attested from 1847. Related: Pyrotechnical (1610s, from pyrotechny "use of gunpowder," 1570s).
