Origin of radical
synonym study for radical
historical usage of radical
Latin rādix comes from wrād-, one of the variants of the Proto-Indo-European root wrād, werād, wred- “root, branch.” From this same variant Latin also has rāmus “branch” (the root, so to speak, of English ramify ); Greek has rhádix (stem rhádik- ) from the same variant. Another variant of the root is the possible source of Greek rhiza, source of English rhizome (Greek variants include Aeolic briza, brisda and Mycenaean wriza ). Wrād- regularly becomes wrōt- in proto-Germanic, the ultimate source of the English word root.
