Today i would like to discuss about the differences in speaking English between the US and UK.
The simplest examples of the differences you need to keep in mind in the two languages is that some words are written with different letters. In the UK for example it is “optimising” while in the US its called “optimizing.” There are other textual differences to keep in mind that go beyond using different letters in the same words. Did you know that what you call a “bathroom” in the US is mostly called a “loo” or “toilet” in the UK? Or an ATM is a “cashpoint?” It can even get complicated. A “bandaid” in the US is a “plaster” in the UK, where plaster in the US is what you use to patch walls with (or in slang, “plastered” means really, really drunk).
In general you can say that UK English usually is a bit more “formal” and feels more like a “written” language where US English is more of a “speaking” language. You can actually hear people saying it when you read it.
Keep in mind that if you are optimizing for Europeans and you are still using the English language that most Europeans are taught the “standard English” version, which means the British one.
