What does 'code-switching' refer to?

Code-switching refers to the phenomenon where speakers alternate between two or more languages or language varieties in a single conversation or interaction. This practice is common among bilingual or multilingual individuals who utilize their linguistic repertoire according to the context, audience, or topic of discussion. For example, a speaker might switch languages depending on the person they are speaking to, the subject matter, or to express a concept that is better conveyed in one language over another.

This ability to switch languages seamlessly reflects not only linguistic skill but also cultural adaptation and social identity. In diverse linguistic environments, code-switching can serve various functions, such as signaling in-group membership, expressing emotions, or demonstrating cultural fluency.

In contrast, teaching grammar rules is a more focused instructional approach that does not involve the dynamic language interplay characteristic of code-switching. Similarly, using technical jargon pertains to specific vocabulary related to a field or discipline and does not encompass the practice of alternating languages. Lastly, speaking only one language at a time contradicts the very idea of code-switching, as it implies a lack of linguistic flexibility.
