Code Switching and Mixed Language Genesis in Tiwi

<p>Data from the transcript of a public meeting are used to examine patterns of code switching in Tiwi, a head-marking polysynthetic language of northern Australia where an N-V mixed language has emerged among younger speakers (Lee 1987, McConvell 2008). McConvell’s theory predicts that code switching behavior should reflect the same center of gravity principles as found in the  resulting mixed language. In particular, a head-marking language like Tiwi should most commonly provide the verbal part of code-switched utterances. Although the corpus used here is too small to draw definitive conclusions, the data do not support the supposed connections between morphological typology, code switching, and mixed language genesis. Reasonable interpretations of the data show no preference for code switching that retains Tiwi’s verbal subsystem, as predicted by McConvell’s center of gravity model.</p>
