Final answer:
The Angles, Saxons, and Jutes brought Old English to the British Isles during the fifth century.
Step-by-step explanation:
During the fifth century, the Angles, Saxons, and Jutes, who were Germanic tribes from the areas around present-day northern Germany and Denmark, invaded the British Isles. The language that they brought with them was Old English, which was a Germanic language that formed the basis of the English language we are familiar with today. This Old English was distinct from Latin, which was the language of the Roman Empire and the Celtic languages spoken by the native Britons.
