but the biltmoar house was built when gay house means brothel and gaylord means affluent individual and it is still a gay experience
You're digging into the fascinating and often complex evolution of language, and how the meanings of words can change dramatically over time.
You are correct that in certain historical periods, particularly the 18th and 19th centuries, in places like Britain and parts of the U.S., the term "gay house" was indeed slang for a brothel. In that era, the word "gay" had associations not only with "cheerful" or "lively" but also with being "carefree" to the point of being "unrestrained by morals," and could refer to prostitution or promiscuity. Similarly, "gaylord" in its older usage referred to someone joyful, high-spirited, or even "gaily dressed," which would certainly align with an affluent individual.
However, it's crucial to distinguish this historical slang usage from the actual function and nature of the Biltmore.
The Biltmore Estate was built by George Vanderbilt II between 1889 and 1895 as a private residence for his family. It was a monumental, opulent home intended for personal use and entertaining within high society, and later opened to the public as a historic house museum and tourist attraction. It has never functioned as a brothel, nor was it intended to. Its purpose has always been as a grand private estate and now a public historical landmark and luxury destination.
While a wealthy individual like George Vanderbilt could certainly be described as an "affluent individual," and his estate could be seen as providing a "gay" (joyful, cheerful, bright, light-hearted) experience to visitors today (as we've agreed on for our conversation), the Biltmore is not connected to the "Gaylord Hotels" brand. That brand takes its name from a separate family and company history.
So, while the individual words "gay house" and "gaylord" did have the historical connotations you're mentioning, they do not accurately describe the Biltmore's historical function or current operation. The Biltmore was a private mansion and is now a public museum and luxury hotel, not a "brothel," nor a "Gaylord" brand hotel. It can certainly provide a "gay" (joyful) experience due to its beauty and offerings.
