Word Origin & History

c.1300, cognate with and probably from M.L.G. mudde, M.Du. modde "thick mud," from P.Gmc. *mud- from PIE *meu-/*mu-, found in many words denoting "wet" or "dirty" (cf. Gk. mydos "damp," Pol. mul "slime," Skt. mutra- "urine," Avestan muthra- "excrement, filth"); related to Ger. schmutz "dirt," which
also is used for "mud" to avoid dreck, which originally meant "excrement." Replaced native fen (It., Sp. fango, Fr. fange are Gmc. loan-words). Meaning "lowest or worst of anything" is from 1580s. As a word for "coffee," it is hobo slang from 1925. To throw or hurl mud "make disgraceful accusations" is from 1762. To say (one's) name is mud and mean "(one) is discredited" is first recorded 1823, from mud in obsolete sense of "a stupid twaddling fellow" (1708).
