Etymology

It is Middle English mudde, mode,[2][3] probably borrowed from Middle Low German mudde (“thick mud”) or Middle Dutch modde,[2][4][5][6] from Proto-Germanic *mud-,[4][2] cognate with Middle High German mot, bog, and Swedish modd.[2][5] Etymonline relates it to a PIE *(s)meu-, found in words for wet or dirty, such as Greek mydos, damp;[4] Barnhart compares Irish mothar, bog.[2] Welsh mwd is from English, and the older English word is fen.[4]
