When Languages Change: Sociolinguistic Studyof Diglossia, Bilingualism, Multilingualism,Code-Switching

Abstract

This article explores diglossia, bilingualism/multilingualism, and
code-switching in multilingual societies to understand the social
functions and identities associated with language use. These three
concepts play a crucial role in sociolinguistics, providing insights
into how language functions in communication and in shaping
social and cultural identities. The purpose of this study is to identify
the role of each of these linguistic phenomena in a social context.
Using qualitative methods through a literature review of various
sources, including theories from leading linguists such as Charles A.
Ferguson, Joshua A. Fishman, and Carol Myers-Scotton, diglossia
reflects social division through “high” and “low” languages;
bilingualism allows for linguistic flexibility without rigid functional
rules; and code-switching is used to adapt communication to social
or emotional situations. These phenomena highlight the importance
of language as a tool for communication and identity in multilingual
societies.
