What is code-switching?

Code-switching refers to the practice of alternating between different languages, dialects, or speech styles within a conversation or discourse. This phenomenon often occurs among bilingual or multilingual speakers who switch from one language to another based on the context, audience, or topic of discussion.

The correct answer identifies code-switching as a process where individuals shift speech tone or formality. This illustrates how speakers may adjust their language usage to fit the social setting or to convey different meanings or relationships with their audience. In many cases, such shifts are inherent to the cultural identity of the speaker and reflect their adaptability in navigating different linguistic environments.

The emphasis on tone or formality is significant, as it demonstrates how speakers might switch to a more formal style in professional settings or adopt a casual tone when speaking with friends. This adaptability is a key characteristic of effective communication in diverse social contexts.
