Which term is exemplified when a bilingual speaker inserts a word from one language into a sentence spoken in another language?

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

Answer: (C)

Codeswitching is when a bilingual speaker alternates between languages within an utterance. When someone inserts a word from one language into a sentence spoken in another, that is codeswitching in action. This can happen to express a concept more precisely, to signal identity or group belonging, or to fill a lexical gap when a term exists more naturally in one language. The other terms don’t fit: interlanguage describes a learner’s developing, intermediate grammar; context-embedded communication isn’t a standard label for this phenomenon; and presentational refers to how information is delivered rather than how languages mix within speech.
