köken: Inherited from Vulgar Latin *drasca, drachia, *drascum, possibly borrowed from Celtic. Or, of Germanic origin, related to either German dreschen / English thresh, to Trester / drast or Drüsen / dross.
köken: Deverbal from помивам (pomivam, “to wash out”) (formally reflecting as earlier *pomyja). Related to Russian помо́и m pl (pomói, “swill, slops”), Polish pomyje (“slops, swill”), Old Church Slavonic помꙑѩ (pomyję).
