The paper discusses the complex role of ethnicity in the construction of a peer-based social order in preadolescence, and argues that the indexical value of "ethnic" variables is constructed among, rather than simply within, ethnic groups, and hence incorporates concerns that span ethnic boundaries. In Northern California, white Anglo speech is showing a split in /ae/ as it raises before nasals and backs elsewhere, while Chicano speakers commonly back both classes of /ae/. Based on ethnography in two Northern California elementary schools, this paper shows that the Chicano pattern does not simply index ethnicity, but indexes place in the peer-based social order as well, and as such is available to speakers regardless of ethnicity.1 All names, of schools as well as of individuals, are pseudonyms. doing, I follow Jürgen Jaspers (this volume) in pointing out that not only can the notion of ethnolect serve to reinscribe popular ideologies, it also belies the constructed nature of linguistic varieties and of social (in this case ethnic) categories. The term ethnolect (like sociolect and the more generic dialect) reflects a view of language as a fixed rather than fluid entity, and of identity as compartmentalized, allowing one to think of an ethnolect as a discrete system indexical of ethnicity alone. The emphasis in this paper will be on the fact that speakers of so-called ethnolects do not live or speak in isolation, and even if the ethnolect is highly reified, its existence depends on a fairly restricted set of resources. The linguistic resources that ethnolectal speakers deploy in their day-to-day lives are not all specific to the ethnic category, and those that appear to be specifically ethnic can index far more than ethnicity. By examining one feature of "Chicano" and "Anglo" English among students in two elementary schools in Northern California, I will show how ethnically distinctive ways of speaking emerge out of shared social practices, in interaction with each other, and have indexical values that are associated not simply with ethnicity but with those shared practices as well.
