Old English (OE) emerged as a distinct language spoken by Germanic settlers in Britain from the 5th-11th centuries. It was divided into four major dialects, with the West Saxon dialect becoming the standard due to the influence of King Alfred. OE had a complex system of vowels, consonants, and grammatical inflections. It borrowed vocabulary from Latin, Celtic, and Scandinavian languages. Key texts like Caedmon's Hymn were written in OE, preserving the language until Norman French replaced it after the 11th century Norman conquest of England.
