Which term describes the phenomenon of alternating between two languages or dialects within a single sentence or discourse?

• A. Interlanguage
• B. Interpretive
• C. Codeswitching
• D. Context-Embedded Communication

Answer: (C)

Codeswitching describes alternating between two languages or dialects within a single sentence or discourse. This happens often in bilingual speakers who switch languages to express a concept more precisely, fill a lexical gap, or signal social meaning or affiliation. It can occur at the level of a word, a phrase, or an entire clause and is a natural, purposeful tool in communication, not a sign of confusion. Unlike terms that refer to a learner’s evolving language system, codeswitching is about how speakers move between languages in real time to convey nuance, emphasis, or cultural identity. For example, a speaker might say, “Voy al supermercado, and luego te llamo,” mixing Spanish and English to suit timing and context.
