vernac
adj.— «Through their circulation among a fluent English-speaking, often convent-educated community, these joking questions highlight the processes of insider/outsider demarcation common to stereotyping in general. They characterize, for instance, the Tamilian or the Gujarati as having pronounced regional accents when speaking Enlish (creating thus the figure of “the vernac.”)» —“Character Stereotypes” by Leela Prasad South Asian Folklore Mar. 1, 2003.
