Etymology: Radiolarians are named for "Radiolaria," a taxonomic group coined in Latin-based scientific terminology from "radiolus," a diminutive of "radius," meaning a small ray or spoke. The name points to the radiating, spoke-like skeletal patterns that many of these organisms build from silica. The word itself is simply the group name with an English suffix attached. The suffix "-an" has a long pedigree. It descends from a Proto-Italic form "-ānos," passed into Latin as "-ānus," and reached English through Old French "-ain" and Middle English "-an." Its job is to turn a noun into an adjective or a noun denoting a member of a group, which is why "radiolarian" means "one of the Radiolaria."
