igneous 英 [ˈɪgniəs] 美 [ˈɪɡniəs]
adj. 火的；[岩] 火成的；似火的
- You might remember this one from earth science class. An igneous rock is one that forms through intense, fiery heat––usually in a volcano. It starts out molten (so hot it melts into liquid), then solidifies as it cools. So, it’s rock that has “ignited.”

- igneous (adj.) 1660s, "pertaining to or resembling fire," from Latin igneus "of fire, fiery; on fire; burning hot," figuratively "ardent, vehement," from ignis "fire, a fire," extended to "brightness, splendor, glow;" figuratively "rage, fury, passion," from PIE root *egni- "fire" (source also of Sanskrit agnih "fire, sacrificial fire," Old Church Slavonic ogni, Lithuanian ugnis "fire"). Geological meaning "produced by volcanic forces" is from 1791, originally in distinction from aqueous. Earlier in the sense "fiery" were ignean (1630s), ignic (1610s).
