What is "code-switching"?

Code-switching refers to the practice of alternating between different languages or dialects within a conversation or even within a single utterance. This phenomenon occurs frequently in multilingual communities where speakers shift their language depending on the context, audience, or topic being discussed. Code-switching can serve various social functions, such as emphasizing a point, expressing identity, or facilitating communication in mixed language environments.

The concept is rooted in linguistic and sociolinguistic studies, highlighting that language is not just a system of rules but also a means of social interaction. This practice can signal a speaker's cultural background, group membership, or levels of comfort with different languages or dialects. Understanding code-switching is essential for educators and language learners as it sheds light on how bilingual speakers navigate their linguistic repertoire in real-life contexts.

The other choices do not accurately describe code-switching. The technique for correcting grammatical errors, methods for teaching vocabulary through song, and strategies for teaching reading comprehension, while valuable in their respective contexts, do not encompass the linguistic practice that code-switching represents.
