Did Angles influence the development of English in Old Period?

It's not entirely accurate to say that the Angles directly "influenced" the development of Old English. It's more accurate to say that the Angles, along with the Saxons and Jutes, were the _founders_ of Old English.

Here's why:

* Anglo-Saxon Migration: The Angles, Saxons, and Jutes migrated to Britain from the regions of modern-day Denmark, Germany, and the Netherlands, respectively. They gradually displaced or assimilated the existing Celtic population, establishing kingdoms in what is now England.

* Language Divergence: The languages spoken by these Germanic tribes, known collectively as "Old English," diverged from their common ancestor (Proto-Germanic) over time. The Angle language, in particular, had a significant influence on the vocabulary and grammar of Old English, leading to the name "Anglo-Saxon" to describe the era.

* Influence on Grammar and Vocabulary: The Angles contributed a significant number of words and grammatical features to Old English. For instance, the word "angle" itself is derived from the name of the tribe.

* Regional Differences: While the Angles had a strong influence, Old English was not a single, uniform language. Regional dialects existed, and some words and features were more prevalent in certain areas than others.

In summary, the Angles were not simply influencers but were the primary contributors to the creation of Old English. Their language, along with the languages of the Saxons and Jutes, formed the basis for the development of the English language as we know it today.
