English is spoken by 750 million people all over the world. It is spoken as either the official language, second language, or foreign language. English is spoken most by non-native speakers.

English is a West Germanic language of the Indo-European language of the Indo-European family of languages. Old English was a group of accents that show the various origins of the Anglo-Saxon kingdoms of England. The English language was exposed to a big change in the Middle Ages. Old English was similar in grammar to other old Germanic languages. They are not understandable for modern speakers. Two waves of invasion caused a transformation in English language. The first one was done by speakers of the Scandinavian branch of the Germanic language family, who conquered and colonized some regions of Britain. The second one was the Norman invasion. The people who spoke Old Norman developed an English variety of Anglo-Norman. A big property of vocabulary in English comes from Anglo-Norman directly. Close contact with Scandinavians caused an important grammatical simplification and lexical enrichment. Old Norman language was in influent in the church, the courts and government. The most famous surviving and the first work from the Old English period is the poem “Beowulf”. The writer is not known. Today, native speakers would find Old English unintelligible but they can overcome this by studying it as a separate language. English remains as a Germanic language because half of its words come from German language. Their lexical roots were very similar but their grammars were more different. English language grammar was influenced by contact with Norse colonizers and this caused morphological simplification of English, the loss of grammatical gender. The old English period ended after the Norman Conquest. The language was influenced by the Normans very much. The English language changed enormously during the Middle English period both in grammar and in vocabulary.

English had a declension system which is similar to Latin, German or Icelandic. Old English distinguished between the nominative, accusative, dative and genitive cases. Besides, the dual was distinguished from the more modern singular and plural. Accusative and dative pronouns merged into a single objective pronoun and this simplified the declension in English grammar throughout the history of English Grammar.
