English, this sole word describes more than just a country, a type of people, or their language. When it is read, it's like if you where reading through time, its incredible to think, that the language English, as we know it today was completely different two hundred years ago. Even more so five centuries ago, and what was considered English ten centuries back in time, would be unreadable to anyone but a scholar of this subject today. Why did it change? How did it evolve? That is what history is here to tell us, almost every word you read was changed more than ten times to what it is now today, to be able to understand this, we must travel fifteen centuries back, to post Roman era England, where what is now called "Old English" emerged from the conjunction of hundreds of Anglo-Saxon dialects.
One of the most interesting peoples that played a part in the creation and molding of the English language and that are still around today are the Celts. Their incredibly rich and varied dialects where adopted by the Britons in the early 1st century BC, when the Celts themselves invaded England. All of the Britons at that time began to speak Celtic dialects, and went by day to day following Celtic laws. But interestingly, even though the Celtic "stay" in England still basically goes on to this day, the Celtic language never really had a large, groundbreaking effect on "Old English". Instead, most of the Celtic dialects developed into what is Gaelic and Welsh today.
There are many reasons for this, but first, it is needed to see where the Celts where coming from and how their Arch-Enemies, the Romans, almost grinded their culture and people inexistent. .
The Celts, where a rather large civilization living in many parts of Europe. Their language was derived from the Anglo-Saxon territories they conquered, each new place they took added or changed the words in the Celtic vocabulary. They where conquerors, with vast territories of land under their rule, but on the other hand lacking the tightly knit political structure that could keep such vast territories under control.
