If you search for “en-suite” in Wikipedia.org, you will automatically arrive with NO “disambiguation” arrive at the word BATHROOM. Quite hilarious to me, I think we should more appropriately use the world classification and sincerely pretentious. “la toilette”
Anyway you do in Wikipedia you end up in the Bathroom, or if you are a seasoned traveler and tired of having the Europeans annoy you, you will finally capitulate and stop saying the word “Restroom” or “Bathroom” and replace it with "Toilet.”
I like restroom, not so harsh, however for he sake of disambiguation I use the word “Toilet.” now because it is globally understood.
I truly believe the word “En-suite” belongs in the Toilet with all the other too vague and confusing terms in the global world.
So what does en-suite mean? Still not too clear to me, however I believe the use of the term is analogous to the USA people using the term “Restroom.” We really should not use this term in a global world, it is un-clear to the world, we need to use the word “Toilet.” However, I think the Brits have somehow hooked on to this Frenchie word, and use it to describe something…, I will never use the terms, except when I am speaking French where it is appropriately used.
So if you are curious, go to this page that I think may explain it, however take care, they lost me… hehehe
