词源

Borrowed from German Graupel(wetter) (literally “graupel (weather)”). Graupel is a back-formation from graupeln (“to hail (with soft hailstones)”) + -el (diminutive suffix); and graupeln is from Graupe (“hulled grain, pearl barley”) (ultimately from Proto-Slavic *krūpà (“grainy substance; groats; hail”) and Proto-Indo-European *krewp-) + -eln (suffix forming verbs, often with a diminutive or frequentative sense).
