Linguistic identity refers to the way in which individuals perceive and express their connection to language as a core aspect of their identity. This research area explores how language shapes personal and social identities, and how individuals navigate their linguistic affiliations in diverse social contexts. It examines factors such as linguistic backgrounds, language attitudes, and language use patterns in relation to cultural, social, and political identities. Researchers in this field often use a combination of qualitative and quantitative methods to study how linguistic identity is constructed, negotiated, and maintained in different settings. Additionally, they investigate how linguistic identity intersects with other aspects of identity, such as gender, race, ethnicity, and nationality.
