What does sud mean?
Sud is an archaic Scottish and northern English word for sweat. As a noun, it refers to the moisture produced by the body, particularly during exertion, heat, or anxiety. As a verb, it means to sweat. The word is uncommon in contemporary standard English, but it has a compact, traditional quality and can be useful when a writer wishes to evoke regional speech or convey the physical immediacy of perspiration. Although it is not related to the more familiar plural noun suds, the two words share a historical connection through older English and Scots forms. Sud should not generally be treated as a general synonym for sweat without a reason for selecting its regional or historical character, since sweat is the ordinary modern English term.
Sweat or perspiration, especially that produced through exertion.
"Dry mud clung to the sud on his boots."
