Language Log » Can a dead language be revived?

@glynmoody for more on the creation of modern Hebrew see "Language in Time of Revolution" by Benjamin Harshav (likely out of print) - details the process of creating a modern language from liturgical roots, including deciding how to "officially" pronounce it https://www.ucpress.edu/book/9780520079588/language-in-time-of-revolution
Language in Time of Revolution

This book deals with two remarkable events--the worldwide transformations of the Jews in the modern age and the revival of the ancient Hebrew language. It is a book about social and cultural history addressed not only to the professional historian, and a book about Jews addressed not only to Jewish readers.
