Like so many other myths

 "golf" is not an acronym for "gentlemen only, ladies forbidden." If you've ever
heard that, forget it immediately. Better yet, find the person who told you and let
them know it's not true.
 By the 16th Century, the word "golf" had emerged.So why do so many people continue
to spread the myth that "golf" is an acronym for "gentlemen only, ladies forbidden"?
Like so many other myths (or what in modern times we might call "urban legends"),
this is one that is very hard to kill off.
It's likely that that the myth of "gentlemen only, ladies forbidden" arose as a joke
made by golfers during earlier times, in the late 19th century or early 20th
century, when no-women-allowed golf clubs were far more common than they are now. In
other words, golf's sexist past is the origin of the "gentlemen only, ladies
forbidden" myth; rather than "gentlemen only, ladies forbidden" being the origin of
the word "golf."
Plus, the history of golf gives the myth a veneer of believability. After all, for
long parts of its history, golf was a sport dominated by men and rarely played by
women. Even after women began playing golf in greater numbers, many golf clubs and
courses restricted or even banned membership by women golfers. In fact, golf clubs
still exist today that do not allow female members.
