The earliest form of English is called Old English or Anglo-Saxon (AD 550- 1066). Old English developed from a group of Germanic dialects in Beihai, which were originally used by Germanic tribes (called pronghorn, Saxon and jute) in frys, Lower Saxony, Jutland and the southern coastal areas of Sweden.
From the 5th century AD, the Anglo-Saxons settled in England, and Rome's economy and administration collapsed. In the 7th century, the Germanic language of Anglo-Saxons ruled Britain, replacing the language of Roman Britain (43-409 CE): ancient Britten, a Celtic language and Latin, was brought to England and occupied by the Romans. Ying Ying (originally? Nglaland and? Nglisc) is named after the angle.
Old English is divided into four dialects: Anglo dialect (Mercia and northumberland) and Saxon dialect, Contos and West Saxon. After the educational reform of King Alfred in the 9th century and the influence of Wessex Kingdom, West Saxon dialect became the standard written language. The epic Beowulf was written in West Saxon, and the earliest English poem Song of Cadmond was written in Northumberland.
Modern English mainly comes from Mercia, but Scottish comes from northumberland. Some short inscriptions in the early days of Old English were written in runes. In the 6th century, Latin letters were adopted and written in the form of semi-informal letters. Including the rune letters Wynn and thorn, and the modified Latin letter ETH? d？ , and ash.
Old English is very different from modern English, which is difficult for English users in the 2nd/kloc-0th century to understand. Its next of kin is old Frisian. Nouns, adjectives, pronouns and verbs have more inflected endings and forms, and the word order is much freer than modern English. Pronouns in modern English have a case form, and some verbs are deformed, but old English also has a noun suffix, and verbs are more personal and number suffixes.
