Baba Malay Diverging trends in two ecologies Nala H. Lee National University of Singapore, Singapore Tis article sheds light on the systematic diferences between the variety of Baba Malay spoken in Malacca and that spoken in Singapore. In the litera- ture, the creole is usually discussed as if it is a single homogeneous variety. Language documentation work conducted in both Malacca and Singapore shows that there are crucial diferences between how Baba Malay is spoken in both places. Tese diferences are systematic, and they pervade areas of morphology and syntax. All diferences lead to the same conclusions. Evi- dence shows that the variety of Baba Malay in Malacca is much more heav- ily infuenced by its lexifer, Malay, than the variety that is spoken in Singapore. Singapore Baba Malay is also more infuenced by its substrate, Hokkien, than Malacca Baba Malay. Tis divergence between the two vari- eties is attributed to their specifc ecologies. Crucially, the impetus for estab- lishing two varieties of Baba Malay becomes even more vital than ever, given the fact that both varieties are highly endangered, and that researchers engaged in research on Baba Malay should be aware of both varieties and their social environments in order to fully represent the creole.
