Etymology: Volcanogenic is a modern scientific coinage, built from "volcano" and the suffix "-genic," meaning "producing" or "originating from." The suffix comes from Ancient Greek "-genēs," from "génos," meaning "birth" or "origin," and it entered English through French "-gène" and Latin "-icus," the source of the English "-ic" ending. Put together, the word describes anything produced by volcanic activity. The "volcano" half has its own surprising ancestry. The Latin "Vulcanus," god of fire and metalworking, gave Italian "vulcano," which passed into English as "volcano." Ancient Greeks had no such mountain-fire god in that form, and the Latin name is older than the Greek-based suffix used here. The compound is used in geology to describe sediments and rocks formed from volcanic material, such as volcanic ash that settles into layers, rather than from erosion or biological processes.
