Etymology 1

From etiolate +? -ed (suffix forming adjectives); modelled after French étiolé, the past participle of étioler (“to become pale and weak, etiolate”), from Norman étieuler (“to become plant stalks left over after harvesting to be used as fodder or for thatching”), probably from éteule (“plant stalks left over after harvesting, stubble”) + -er (suffix forming verbs). Éteule is derived from Old French esteule (“straw”), from Latin stipula (“plant stalk; plant stalk left over after harvesting, stubble; straw”), ultimately from Proto-Indo-European *steyp- (“to be stiff; erect”).
