Which statement about code-switching reflects its main function?

• A. Interferes with acquisition
• B. Socio-linguistic and communicative competence; does not interfere with acquisition
• C. Is a replacement for the first language
• D. Is a method to memorize vocabulary

Answer: (B)

Code-switching functions as a tool for social and communicative interaction, showing a speaker’s ability to navigate different language resources to convey meaning, manage conversation, and connect with others. It reflects sociolinguistic competence—the skill to decide when and how to switch languages to fit context, listener, and purpose—often helping understanding rather than hindering language development. This is why it does not inherently interfere with acquisition; learners can switch to express nuance and fill gaps while still progressively developing both languages. It’s not about replacing the first language, nor a routine method for memorizing vocabulary, so those descriptions don’t capture its true role in communication and learning.
