Etymology

The term "best-seller" emerged in the early 20th century, combining "best" (from Old English betst, meaning "of the highest quality") and "seller" (from Old English sellere, meaning "one who sells"). It originally described books with exceptional sales, later expanding to other high-demand products. The hyphenated form preserves the compound's clarity, emphasizing the dual emphasis on quality ("best") and commercial success ("seller").
