Entries linking to Garbled
early 15c., "to inspect and remove the dirt and dross from (spices)," from Anglo-French garbeler "to sift" (late 14c.) and directly from Medieval Latin, Catalan, and Italian garbellare, from Arabic gharbal "to sift," related to kirbal "sieve," which perhaps is from Late Latin cribellum, diminutive of Latin cribrum "sieve" (from PIE root *krei- "to sieve"). Apparently the word was widespread among Mediterranean traders (compare Italian garbellare, Spanish garbillare "to sift grain").
In later-medieval Europe, pepper and ginger and some other spices were always imports from the Arabic-speaking Eastern Mediterranean, and the same goes for many botanical drugs, and a few expensive colorants. The spices, drugs and colorants had variable amounts of natural chaff residuals and occasionally had unnatural added chaff. ["English Words of Arabic Ancestry"]
