mucky (adjective), mucker (noun)
Muck dates back to the mid-13th century. The Middle English noun muc or muk originally meant ‘cow dung,’ usually when used as manure, but soon expanded to include any other kind of dung or even vegetable matter, when used as manure. It came into English from a Scandinavian source, probably the Old Norse myki or mykr (cow dung), though some linguists also think that it could have been the Danish møg (also ‘cow dung’). Either way can be traced back to the Proto-Germanic root muk– or meuk- (soft). The more general sense of ‘mud, dirt or filth’ first appeared around the year 1300. The verb comes from the noun and, meaning ‘to remove manure’ as well as, more generally, ‘to dig in the ground,’ dates back to the late 14th century. The meaning ‘to make dirty’ was first used in the early 19th century. The expression to muck about or around appeared around the mid-19th century, while muck up, meaning ‘to make a mess of something,’ dates back to the late 19th century.
