What is the origin of spelunking?

Answer 1

Spelunking, the exploration of caves, derives its name from the Latin word "spelunca," meaning cave. The term gained popularity in the United States in the early 20th century, particularly after the publication of literature and guides on cave exploration. While the practice of exploring caves dates back to prehistoric times, the organized sport of spelunking emerged as a recreational activity in the 1930s and 1940s. Today, it encompasses both casual exploration and scientific study of cave systems.
