Exile in the Language To Hear, to Say, to Write a Foreign Language

What is exile when it means a new language, the most private and precious thing a man and an author has? What does it mean for an author to change languages, to write in a language that is not his mother tongue? This essay is a large reflexion about mother tongue and writing tongue when they differ, along with the novels and works of writers that adopted another writing language: Vassilis Alexakis, Samuel Beckett and Agota Kristof.
