I mainly hear treble rather that triple. Maybe its just a southern England thing

Even moreso that for the US, it's a MASSIVE country with each state being almost akin to it's own country in terms of culture, language, nationality makeup, history, just everything. I'm sure even things mentioned in this video aren't true everywhere here, let along any other generalization. Even breaking things up into general categories of "The West, The Midwest, The South, and The East" doesn't always work.

It's the same way for American number systems. 2 massive generalizations.

And not just with numbers but with pretty much everything. They intentionally make things more complicated than they need to be and sometimes will change "their way" just for the sake of doing it differently from America. For example, "soccer" as a term originated in the UK. I couldn't tell you what logic they gave upon switching to calling it football but it's ridiculous that they criticize Americans for calling it by the term the UK came up with in the first place.

True

we also say “o” in american english to say 0. usually when a singular zero exists in a long string of numbers, me personally i know i say “o” depending on context but im not self-aware of the precise “rubric” on when i use “o” instead of zero.

Dont forget about nil!

I literally say zero and O in the same phone numbers.

@@estergrant6713 I'm British and have used "o" for zero, but I now have a career in enforcement where it is important to get number plates and vin numbers correct. I now try to avoid doing so, using zero for "0" and Oscar for "o".

I'm learning German and they do this too and it is incredibly frustrating.

bibliofanatic You never learnt/heard the nursery rhyme: Sing a song of 6d a pocket full of rye four and twenty blackbirds baked in a pie? English used to use the German way of vier und zwanzig.

Cigmorfil English also used to have Dative case, doesn't mean it's not frustrating to learn because we don't use it anymore.

Instead of being an infective language with changing endings English uses prepositions to indicate the case before the noun (of, to or for, by with or from) - English tells you what's going to happen and then gives the noun whereas inflective languages give you the noun and then what's going to happen; this is why a preposition is a word you never end a sentence with. Due to lack of endings English is more strict over word order, and doesn't (generally) require adjective matching.

I don't think anything beats French word for 90 that is literally "four twenties and ten".

That's because if you go year/month/day when you sort files by date they all end up in order of when they occurred, from the start of the year to the end of the year.

It makes sense in Yu-Gi-Oh since the smallest unit of life points was 100, so speaking in terms of hundreds was sort of natural.

It's over ninety hundred!

Actually, certain cards do deal damage with a 50 on the end, so you might have 50 life points.

I’d call dealing 50 damage the exception to the rule. Most typically, the game deals with 100 hit point increments.

For me it was the fifteen hundred metres in athletics. Eight hundred metres made sense, so I had to think of it as 800 metres scaled up. That's still the way I make sense of it.

I never thought to think about that but now I'm desperate to know what the highest house number in Britain is haha my old house was in the 170s (scotland) and I'm sure the road must have got beyond 200 because that house was only halfway down it

@Koholos You kind of start counting at 20 (zwanzig). Not sure if that's connected, but I always count things in multiples of twenty too, you start by 20, count to 39, and then start again at 20 and count the times you cycled through

@Koholos its actually very accurate to a second if you say it normally

Same in Dutch (één-en-twin-tig, twee-en-twin-tig, drie-en-twin-tig). To me this feels a lot more natural than Mississippi or Piccadilly because the four syllables give a nice four-beats-in-a-bar rhythm

It's another compound. It's not a unique word, it translates to '1 and 20, 2 and 20'

HunterShows Yeah... I ask myself why we germans do that... it's just weird and I have to think twice on english numbers as well XD

What's also SUPER confusing and makes me struggle every time is the weird thing in germany with big numbers... In germany we say Million , Milliarden where in english you say million, billion wich means where im in german at Trillion you in english are already at quintillion... >.

But it's not only German that does it that way round (let's just start a revolution and say "zwanzigundeins" from now on!), it's also the Dutch "eenentwintig", and the Danish "enogtyve" (found the same for Norwegian, but only in one place, the others all list "tjueen" only).

But why call it the 5300 block at all? Just call it the 53 block, you don’t need the hundred

And why do they say 'two thousand one' for dates and not 'twenty hundred one' as with the 5300 example?

I think it is more to do with currency vs patterns. For money you would say 5 thousand 3 hundred because it is a full count. For the year it is about clarity...so two thousand one Etc until double digits...then use a 2x2 pattern "twenty ten" about half the time and "two thousand ten" the other. Phone numbers in patterns unique to the number because patterns are easier to remember: fivefivefive twothree sixthree. Or. 5 5 5 twelve ten. Same for credit cards and addresses...patterns. if it is a zip code, phone number, area code,or address, some areas say "oh" instead of zero. An American might say 12 hundred dollars. But would almost never say 1 thousand 2 hundred for an address. They would say. 4 oh 4 or 4 zero 4. For an address more often than 4 hundred 4 I don't know about other countries, but I have refused to take a new phone number that didn't have a nice pattern or rhythm!

i've found it reliable throughout my life to assume low numbers of one set (odds) means on the other side of the road is the higher numbers of another set (evens). if you're at 3, then you can bet that the other side says 78. the only time i've noticed the numbers climbing up on both sides is on closed streets which don't loop or connect to another road. if it does connect i've noticed it goes up one way and down the opposite. much more efficient for postmen too.

Yeah that’s was I usually observe like my house is 22 and the other side is 23 whereas next door is 24

The reason is because we have historic buildings in the UK. You could have a row of small terraced houses on one side of a road some larger shops or house with bigger grounds on the other therefore the variance can be way out. As new buildings replace others they sometimes need to add a and b on to the numbers to stay In the existing sequence on a road. Saying that many new builds dont have number 13, as it can be considered bad luck.

@@leeramsden3095 No 1 usually would start in the town or cities and as urban growth spread out, the numbers increase. There is another common thing that happens in the uk. There would be one main road between two towns or cities. So where i live it runs from Manchester to Oldham. As the road leaves Manchester it is called Oldham Road, then at around half way the name changes to Manchester road which goes into Oldham.

True.

Triple is common in the U.S. but we still use treble in certain areas of society. For example, laws in the U.S. sometimes refer to 'treble damages' to mean three times the amount of damages. Likely a result of American law being based on British common law.
