How did the language of old English evolve during the dark ages?

During the Dark Ages, Old English evolved significantly due to various influences, including the arrival of the Anglo-Saxons, who brought their Germanic languages, and the subsequent Viking invasions that introduced Norse vocabulary. The Christianization of England also introduced Latin terms and ecclesiastical language. This period saw linguistic changes as Old English absorbed elements from these languages, leading to a more diverse vocabulary and shifts in grammar and syntax. Overall, the combination of these influences laid the groundwork for the transition to Middle English in the later medieval period.
