Old English is divided into four dialects: Anglo (Mercian and Northumbrian) and Saxon, Kentish and West Saxon. Through King Alfred's educational reforms in the 9th century and the influence of the Kingdom of Wessex, the West Saxon dialect became the standard written language.

The epic poem Beowulf was written in West Saxon, and the earliest English poem, Caedmon's Song, was written in Northumberland. Modern English is mainly of Mercian origin, but Scots is of Northumbrian origin. Some early brief inscriptions in Old English were written in runes. By the 6th century, the Latin alphabet was adopted, writing in a semi-informal alphabet.

Main article: Early Modern English

The next period in the history of English is Early Modern English (1500-1700). Early Modern English is characterized by the "Great Vowel Shift" (1350-1700), inflectional simplification and language standardization.

The Great Vowel Shift affected the influence of stress in Middle English. This is a chain shift, meaning that each shift triggers a subsequent shift in the vowel system. Mid-autumn and open vowels are raised, and closed vowels are broken into vowels. For example, the word "bite" was originally the word for "beet" today, and the second vowel in the word "about" is the pronunciation of the word "boot."

Because English retains many spellings from Middle English, the Great Vowel Shift explains many spelling irregularities and also explains why English vowel letters are pronounced differently from the same letters in other languages. Very big.
