摘要：

中世纪早期是英语发展的一个极其重要的时期。在这个时期,由于诺曼人侵入后，法语在英格兰社会，尤其是在统治阶级和上层社会占统治地位,到后来，由于多重原因，英语慢慢变成了全民共用的语言。于是，在这个时期，便出现了法语作为统治阶级和上层社会的语言，英语是普通民众的语言，拉丁多作为宗教和学术语言的三语共用现象。本文针对这一现象，分别叙述三种语言的使用情况，以及互相影响，相互融合的情况，深入探析英语在这一时期的发展过程。本文研究的内容有助于其他英语学习者更深层次的了解英语的发展过程以及这一时期英格兰社会的语言使用情况。

Namely，French was spoken by ruling class and upper class; English was spoken by common people and Latin was the language of the religion. This phenomenon had great influence upon English language. This thesis separately narrated the usage condition of the three languages, and their fusion and influence to each other and deeply analyzed the development of English in this period. The content of this thesis can contribute to the better understanding of the development of English and the language usage of England in this period of other English learners.
