The English language belongs to the Indo-European family and it is very old. It has changed very much throughout the centuries. If you had an opportunity to read Shakespeare, you could obviously notice the difference the English language spoken today and the one of his epoch. Throughout history, other languages ​​have influenced English. Though initially of Germanic origin, it has been in fact replaced around 500 BC by the Celtic language. Celts moved to Britain from the Central and Western Europe. The Celtic language evolved into the Irish and Welsh languages ​​that are spoken today in some parts of the United Kingdom. During the Roman period, A.D. - 43-400, Latin influenced the Celtic language, and some Latin words entered the Celtic language. In 449 the Germanic tribes - the Angles, the Saxons and the Jutes, invaded Britain. All spoke dialects of a language that scholars call West Germanic. Other current West Germanic languages, along with English are Dutch and German. West Germanic was closely related to North Germanic, which survived today in the Scandinavian languages ​​such as Norwegian, Swedish, and Danish. Originally, both West Germanic and North Germanic were the same language, called Germanic. They all spoke Old English, which replaced Celtic. Old English was spoken until the year 1000.The name term English goes back to the name of one of the Germanic tribes - the Angles. During the Norman Conquest of 1066, William the Conqueror imposed a new government, and tried to impose on Britain the conquerors' French. From then until about 1475, the language is called Middle English. During that time English was very much under the influence of French and thousands of French words entered the language. Around the 1475 the English language began to change. A lot of sounds changed their pronunciation and spelling changed as well. Thus, the Modern English appeared. It suffered many changes since 1500 and it continues to develop. Development of science, technology and society in general brings new valuable additions to the language nowadays.
