Kanak Sprak is a German sociolect created by Turkish youth in Germany in late 1980s.
The sociolect takes its name directly from the title of the book Kanak Sprak (1995) by German-Turkish author Feridun Zaimoğlu. Its name means roughly "Kanake-talk", referring to the word Kanake, which is used originally as a racially charged pejorative. The book deals with the idea of reclaiming this term for positive purposes. Other synonymous names for "Kanak Sprak" are "Ghettosprache", "Türkenslang", "Kiez-Deutsch", "Kiezdeutsch", "Türkendeutsch" and "Kanakisch".
