Abstract: Samuel Beckett’s letters are written in diverse langages and addressed to people from multiple countries. He expresses his will to break with his mother tongue, and to adopt another. He often inserts terms from other langages : German, Italian, Spanish, Latin, Greek, Sanscrit, etc., which produces a linguistically multicoloured epistolary style. The correspondance can thus be viewed as announcing the ‘Babelian’ nature of his work.
