It has been suggested that morphosyntax has more constrained social meanings than phonological variation, despite the scarcity of empirical research evidencing this claim. By using frequency correlations to isolate stylized moments of grammatical variation, this paper provides evidence of the rich social meanings constructed by nonstandard11We use the term ‘nonstandard’ to refer to linguistic variants that are not codified in the standardised variety of a language. This reflects usual practice in variationist sociolinguistics. We recognize the hegemony of standard language ideologies and the potential for the term ‘nonstandard’ to further marginalize highly regular and frequent modes of language. However, alternative terms such as ‘regional dialect forms’ do not capture the fact that grammatical items are employed across regional and social styles of speech. Also, as our paper demonstrates, variants identified as ‘nonstandard’ are routinely stigmatized, whereas forms described as ‘regional’ are not always sanctioned in the same way or to the same degree; compare, for instance, the use of negative concord (I didn’t do nothing to mean ‘I didn’t do anything’) with the use of a variant like multiple modals (I might could do it to mean ‘I might be able to do it’). Our use of ‘nonstandard’ is intended to identify variants which undergo prescription precisely because of comparison with standardised alternatives. However, note that we refer to individual nonstandard variants as elements of a person’s diverse repertoire (Snell 2013), without presuming that a specific instance of a nonstandard form equates to speaking in a ‘nonstandard dialect’. grammar. In particular, we show that, whilst definite article reduction (DAR), nonstandard were, and negative concord work together in one British working class young person's speech to produce an intimate, collaborative style, these variants are used strategically to index subtly different states and alignments. We also show that other grammatical variants – use of nonstandard irregular preterit forms and demonstrative them – are not used strategically to convey interactional positioning. The different function of these variants demonstrates the diversity of morphosyntax, raising questions about the relationship between grammar and social meaning, ideology, pragmatics and linguistic processing. We argue that addressing these questions not only benefits our understanding of social meaning across different levels of linguistic architecture, it also provides us with better evidence to advocate for alternative (and more suitable) models of linguistic variability in educational discourse.
