The Postmonolingual Condition

Beyond the Mother Tongue examines distinct forms of multilingualism, such as writing in one socially unsanctioned "mother tongue" about another language (Franz Kafka); mobilizing words of foreign derivation as part of a multilingual constellation within one language (Theodor W. Adorno); producing an oeuvre in two separate languages simultaneously (Yoko Tawada); and mixing different languages, codes, and registers within one text (Feridun Zaimoglu).
