Definition of scum

The word "scum" has a fascinating history. The term originated in Old English as "scum" or "scuman," meaning foam or froth. This sense of the word was likely derived from the verb "scuman," which meant to foam or bubble. Over time, the meaning of "scum" expanded to include other connotations, such as the accumulation of impurities or worthless matter on a surface. In Middle English (circa 1100-1500), "scum" began to take on a derogatory sense, describing the lowest or most despicable elements of society. Today, "scum" is often used as a pejorative to describe someone or something considered vile or contemptible. Despite its negative connotations, the word "scum" is a direct descendant of the Old English words for foam and froth, and its original sense remains an intriguing footnote in the etymology of this versatile term.
