mud

From Middle English mud, mudde, mode, probably a borrowing from Middle Dutch mod, modde or Middle Low German mudde, ultimately from Proto-Germanic *mud-, *mudra- (“mud”), perhaps from Proto-Indo-European *mū-, *mew- (“moist”). Cognate with Saterland Frisian Mudde (“mud”), Middle High German mot (“mud”), Swedish modd (“slush”). Compare also suffixed variants English mother (“vinegar-forming sediment in alcohol”), West Frisian modder (“mud”), Dutch modder (“mud”), German Low German Mudder (“mud”), German Moder (“moldiness, mildew, decay”), Danish mudder (“mud”). Alternative etymology suggests the Proto-Germanic word is possibly borrowed from a Uralic language (compare e.g. Finnish muta (“mud”), Northern Sami mođđi (“mud”), Erzya мода (moda, “earth, ground”) from Proto-Uralic *muďa (“earth”)).

From Dutch mud, from West Germanic, from Latin modius. Doublet of modius and muid.
