While some people assume the word gaming was created as a way to “re-invent” the casino industry, history tells a different story. The word “gaming”—defined as the action or habit of playing at games of chance for stakes—actually dates back to 1510, predating use of the word “gambling” by 265 years. The words “gambler,” “gambling” and “gamble” all were considered slang when they came into use in the 18th century, implying that the activity involved unduly high stakes. The word “gamble” was essentially considered a term of reproach, according to The Oxford English Dictionary, and would only be used by those who “condemn playing for money altogether.”
In 1891, even The Anti-Gambling Association referred to the activity as “gaming” in a publication: “Before the third crusade, there was no check upon the gaming vice, and no limit to the stakes. … During subsequent reigns gaming, although generally condemned, was vigorously pursued.”
Casinos in Nevada have been referred to as part of the “gaming” industry ever since they were legalized there in 1931. As the industry expanded outside of Nevada, it continued to carry that name. As opposed to the business term “gaming,” the word “gamble” is now commonly used to refer to the actual activity. A 1987 reference dictionary uses the two terms interchangeably, defining gaming as “the playing of games of chance for stakes; gambling.”
