This is not a book meant for those thousands of scholars whose scholarship and erudition is beyond calculation but for those hundreds of thousands of students who have perhaps, a little familiarity about the origin and development of the language which they use from street to Therefore, my sole objective of writing this book is to acquaint the readers about the glorious history of English language, her origin, development, odds and setbacks it confronted in the process of making. The singular feature of this book is that every single fact has been elucidated so simply as to make comprehensible to the the readers irrespective of their scholarship and concise and simple as possible and illustrative examples have been given of each point dealt with. The inclusion of socio- political events and historical events in the present book makes it more simple, vivid and ascertainable. They are intended to serve a purpose of tangibility and the aim of the book as a whole, the complete information about the facts. Being student of English Literature it is utmost necessary to know the origin of English language and its structure, varieties and importance in the society. Succinctly saying the book has recorded the events and journey of English language from a dialect to established language. Sincere thanks are due to those authors, Youtubers, whose books and videos have been consulted. Suggestions and comments for making pertinent improvements and making it more reader-friendly will be greatly appreciated.
