Citations for igneous
In the distance, an igneous flash spread silently through the clouds, flaring in great yellow pools, lighting the desert floor and the cactus and mesquite and the greenery that was trying to bloom along a riverbed that never held water except during the monsoon season. James Lee Burke, Feast Day of Fools, 2011
I understood in a last vital spurt that flame consists of a splendid clarity, and unusual vigor, and an igneous ardor, but it possesses the splendid clarity so that it may illuminate and the igneous ardor that it may burn. Umberto Eco, The Name of the Rose, translated by William Weaver, 1983
Origin of igneous
Igneous derives from the Latin noun ignis “fire” (inflectional stem igni-). It is one of the Proto-Indo-European words for “fire” and is closely related to Slavic (Polish) ogień (inflectional stem ogni-) and Sanskrit agni- “fire,” the Vedic god of fire. Another Proto-Indo-European word for “fire” appears in Germanic (English) fire, ancient Greek pŷr, Hittite paḫḫur, Slavic (Czech) pýř, and even Latin pūrus and impūrus “pure” and “impure” (“fired” and “unfired”). The word entered English in the 17th century.
