“... the master bedroom is now called the PRIMARY bedroom.”
“Owner’s suite” was in use for a while, since most “master bedrooms” had an attached bathroom. However, that’s also racist ... slave-owner’s suite! ... and also discriminates against renters, who might feel they couldn’t use the rooms because it’s the “owner’s suite.”
And a “En Suite” is french and will sneer at your pitiful attempts at decorating.
