General rule of thumb is, if the word was around before the Americas were discovered, then British pronunciation is always correct :)

27 years in the British military here.  British people saying that we say "Loo" are incorrect and have picked that up from American movies. We say Left-tenant. The origins of the word are in the old French rending of the word Lieu was Leuf.

If you said 'Boo-ee' on a British boat, the crew would collapse in a state of near-terminal hysterics!

a missal can be  a missile if you throw a prayer book at someone.

In the U.K., we pronounce our words very differently depending on which town or city we are from. Accents vary quite significantly across the U.K.

As an Aussie, it was fun to watch- we pronounce some the American way, but most often we use the British pronunciation- and in terms of the word “buoy” I’ve always assumed we pronounce it “boy” because it’s related the the word “Buoyant”

There is the whole "on accident" vs "by accident" thing that gets me.

Americans dont understand how other letters affect the Ay and Ah sounds in words, so funny. We learn this in Primary School.

for anyone wonder, the reason we in britain say "Leftennant" insted of "Lootenant" is because our word, even though the spelling was updated to modern french, is pronounced using OLD french "Leuf" instead of the modern "Lieu" - it is still correct, just archaic.

The American pronunciation of Dy-nasty is a My-stery

It doesn't matter the British language came first so by default Brits are correct

People the British way sounds better
That's because it's our language & we speak it correctly🤣

Before I even started the video, I knew that UK 🇬🇧 pronunciations would match with Australian 🇦🇺 pronunciation. When the USA 🇺🇸 went to war with England, they wanted to spell and say things a "new" way, in the "new" world. Countries like Canada, India and Australia maintained the connection to Commonwealth, and respectfully, maintained the language.

I am from Singapore where i was raised to speak British english. when i moved to the states i was horrified at American arrogance correcting my  pronunciation!

As an English woman I found this hysterical. Nice that you tried to work out the differences. What you need to remember is that the English language evolved over many centuries and a lot of the words we use come from Latin, French, German, all of the countries that invaded us over time. Words like niche come from the French and is prounced is a slightly French way. I think you should study the origins of the words, you'd find it interesting

Tyler, all of these are simple stress shifts within the words. No magic required

As a Canadian it drives me crazy when people say "nitch", instead of niche.  It's definitely a way to spot someone from the US.

The word lieutenant is French and comes from the words lieu meaning place and tenant from the verb tenir meaning to hold. The old French word for place was luef. So the Brit prononciation comes from old French lueftenant.
Don't forget that the UK was under Norman rule for centuries and French was the official language.. or a form of it. Norman or old French.

The word, logically, is pronounced 'lootenant' in the USA, but in English it is pronounced 'leftenant', possibly derived from luef, the Old French for lieu. Lots of words derive from French or Latin in our language.

Winston Churchill, once referred to American and England as two Nations divided by a common language.  This rather insightful video rather shows how right he was.
