This paper provides the first overview of the history, sociolinguistics, and structures of NamibianKiche Duits(lit. “kitchen German”), which is today a dying contact variety. The analysis draws on archival records, colonial publications, and memoirs, as well as over 120 sociolinguistic interviews conducted in 2000. Early varieties of NamibianKiche Duitsemerged from 1900 under German colonial rule. The language was used primarily for inter-ethnic communication within the work context. However, speakers also “crossed” playfully intoKiche Duitsin a number of within-group speech genres (competition games, scolding, banter, etc.), thus appropriating the colonial language—alongside cultural borrowings (Truppenspieler, “traditional” dress)—for new in-group practices. These within-group uses contributed to the linguistic stabilization of the language as well as the formation of new (post-)colonial (neo-African) identities.*
