InLiSt No . 6 Interaction and Linguistic Structures From Code-switching via Language Mixing to Fused Lects : Toward a Dynamic Typology of Bilingual Speech
I would like to thank Li Wei, one of the organizers of the conference, for his encouragement to turn the lecture into writing. Previous versions have also been presented and discussed at the Universities of Berlin (FU, JFK-Institute) and Barcelona (Univ. Autonoma). Thanks also to Elizabeth Couper-Kuhlen, Monica Heller and Yaron Matras for critical and helpful comments. II In recognition of the enthusiasm he has brought to all aspects of the study of spoken verbal interaction, we dedicate this series to Professor Dr. Introduction Over the last few decades, a wide range of phenomena have been described in which two languages are juxtaposed in discourse and/or within a sentence, variously called language alternation, code-switching, code-mixing, etc. It seems worthwhile (and possible) at this stage of research to consider the ways in which these phenomena may be subject to a typology. The present paper aims at such a typological approach. A continuum of language alternation phenomena will be presented which spans out between three well-documented cases (conceived as prototypes) which will be labelled code-switching (CS), language mixing (LM) and fused lects (FLs), with CS and FLs representing the polar extremes of the continuum and LM a point inbetween. Since these three prototypes have been amply documented in the literature,the continuum rests on relatively secure empirical grounds. However, I will also suggest an interpretation of it which is somewhat more tentative, i.e., to see the continuum CS —> LM —> FL as a case of structural sedimentation which some might call " grammaticalization ". Particular attention will therefore be given to the transitions, CS —> LM and LM —> FL. The possibility of such transitions has been hinted at, in particular, by Scotton 1988 who suggests that " overall switching as an unmarked choice seems to be the first step to what has been called the development of a semi-autonomous 'Mix' " (165), for which she also uses the term " fused variety " (158). Generally speaking, however, particularistic, differential and historical studies of bilingualism have often been hidden under the more universalistic interests dominating the past decades of research. For this reason, little is known about the dynamic aspects of speech in individual bilingual communities over a period of time. The terms CS, LM and FLs will be used in the following way: CS will be reserved for those cases in which the juxtaposition of two codes (languages) is perceived and …
