Linguistic identity discourse refers to the use and analysis of spoken, written, or other semiotic practices through which linguistic identities are expressed, constructed, negotiated, and interpreted in social contexts ^[1][2]. It encompasses discourse practices that position individuals or groups in relation to social categories and memberships, with identity treated not solely as a fixed attribute but also as an interactional and socially situated accomplishment ^[1]. The concept lies at the intersection of sociolinguistics and discourse analysis, focusing on how linguistic choices and discourse practices index, reproduce, or contest identities rather than treating linguistic identity as equivalent to language proficiency or language use alone ^[1][2].
