smirch

English edit

From Middle English *smorchen ("to spatter, soil"; attested in besmorchid (“bespattered, soiled all over”)), of uncertain origin. Perhaps a derivative of Middle English smeoren, smuren, smeren (“to smear”) or related to Middle English smotry (“sooty, grimy”). Compare also Middle English bismotered (“bespattered, soiled”), Old French esmorcher (“to torture”), Middle English smoterly, smoterlich (“besmirched”), modern English smut.
