The word "thin" originates from Old English þynne, meaning "not thick, rare, or sparse." It shares roots with Proto-Germanic thunnuz and is related to Dutch dun and German dünn. The core concept of "lack of density" has remained consistent across its evolution, extending metaphorically to describe physical leanness, sparse distribution, or diluted substances.
