Modern English consists mainly of loan words from practically every language spoken by men.

The structure of English owes much to Latin and Greek, as is the structure of most Southern European Languages. English also owes much to the Greek Language, and likely going back even earlier, likely has words that go back to Egyptian, Aramaic,Babylon and Abyssinian. There are words in the English Language that originated in every country that people from the UK either visited, settled or traded with.
It's a characteristic of the language that it has a structure that causes it to constantly adapt, change and grow.
Currently they claim there are 1,005,366 words in the language, after June 10, 2009 having announced the 1,000,000th word. This means that 5,366 words have been added to the language in the past approximately 7.5 years, or about 715 words per year. That?s approximately 2 words per day.

It is estimated that about a third of the world?s population, some two billion persons, now use English.
I suggest that it's really a misnomer to continue to call it 'The English Language' It's now a global language and is not in anyway controlled, owned or regulated by the UK.
This is by no means the whole story, but this post is long enough.
I speak as one with a Post-graduate qualification in
TESOL. Teaching English to Speakers of other languages. The History of Languages is fascinating and teaches a lot about the world.
Most English speakers now speak a language which is very Americanised, influenced by Radio, Televisiion, Movies, Music and the internet.
Many younger Australians don't remember or use Australianisms that were common 50 years ago. For example, 'Bloke' has pretty much disappeared and has been replaced by 'Guy' and 'Guys' It's not really English English that's dominating language today, it's
American English.
When I set up a new computer, I have to set a language. The two most common choices are American and UK English. I think
Office still offers 'Australian English' So, if I can't find that I choose 'UK English', because the conventions are closer to traditional Australian Usage. But since most people, including journalists and academics would be using American English, it doesn't matter much. But I still do it anyway.
Yankee. - during and after WWII 'Yankee' was the universal term applied to anybody from the US, in common Australian usage. Took us a while to work out that Southerners' don't take kindly to being called Yankees.
My speech and writing can be very Americanised, sometimes deliberately. Reading American comics and books contributed to that. I often find American 'popular' expressions very apt and too the point. So, you could say I have a love/hate relationship with US English.
Cheers!
