What is the origin of deracinate?
The root of deracinate “to uproot” is the Late Latin noun rādīcīna “root,” from Latin rādīx (stem rādīc-), from which English derives radical and eradicate. Latin rādīx comes from the Proto-Indo-European root wrād- (and its variants) “branch, root.” The noun wrādios becomes Latin rādius “staff, rod, beam, radius (of a circle), ray (of light),” from which, via French, English has ray (of light or energy). The suffixed form wrād-mo- becomes Latin rāmus “branch, twig,” from which English derives ramify and ramification. Proto-Indo-European wrād- becomes wrōt- in Germanic, from which Old Norse derives rōt, which becomes root in English. Deracinate entered English in the late 16th century.
