Glyph origin edit

Phono-semantic compound (形聲／形声) : semantic 火 (“fire”) + phonetic 希, the latter being derived from 稀 (xī, “rare”) of which it is the phonetic element. This is coined in light of the observed lack of hydrogens (as compared to alkanes) in alkenes and the fact that alkenes are flammable.

Compare 烷 (wán, “alkane”), 炔 (quē, “alkyne”).
