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
