I find these to be interesting examples of English word change.
Gay, - In the 50’s it used to mean someone happy. Today it is means ????
Queer - In U.K. English, again back a few years ago, it meant odd, strange, not normal. Today what does this mean ???
There are other less “striking” - not offensive bastardizations of English. Is this good, is this bad ??? History marches on
I'm guessing that gay was a euphemism invented in the inner bowls of NYC trust-fund snobbery, to describe socially critical homosexuals.
