köken: Inherited from Old French reoïlle, from Vulgar Latin *robicla, from syncopation of Latin *robicula, a diminutive of Latin rōbīgō (“rust”) + -cula (from -culus (suffix forming diminutives)). Rōbīgō is derived from rōbus (a variant of rūfus (“red, reddish”)) + -īgō (suffix forming nouns usually denoting diseased conditions). Compare Catalan rovell, Occitan rovilh, Spanish robín.
