Metaphorical code-switching

• abstract: Metaphorical code-switching refers to the tendency in a bilingual or multilingual community to switch codes (language or language variety) in conversation in order to discuss a topic that would normally fall into another conversational domain. "An important distinction is made from situational switching, where alternation between varieties redefines a situation, being a change in governing norms, and metaphorical switching, where alternation enriches a situation, allowing for allusion to more than one social relationship within the situation.
