What is an example of code switching?

The correct answer is switching languages based on the audience. Code switching refers to the practice of alternating between two or more languages or language varieties in a conversation, depending on the context, audience, or social situation.

This can often occur in bilingual or multilingual environments where the speaker may choose to use a particular language that is more accessible or appropriate for their listeners. For instance, a bilingual individual may speak English with friends while using Spanish with family members, depending on who they are communicating with.

Changing the style of signing for ease of comprehension refers more to adjusting one's interpretation style to enhance understanding rather than switching between distinct languages or language varieties. Adjusting vocabulary based on formality could involve selecting words that fit a particular level of formality but does not necessarily encompass the broader concept of code switching, which often involves complete shifts in language. Lastly, using slang in informal settings pertains to colloquial language usage and does not reflect the structural dynamics of code switching between different linguistic systems.
