Four Languages in One Head — Code-Switching

📖 From my experience:
Bengali is my first language. English is my fourth (Sylheti, Hindi, then English). French is my fifth — and Réunion adds Creole as a sixth. Inside my head, languages don’t stay separate. A word in the right language arrives first. Then the grammar of another. Then the feel of a third. This is called code-switching. It’s not a problem. It’s what being multilingual actually is.
🎯 Language focus:
Code-switching = moving between languages (or registers) within a conversation, often unconsciously. It is a natural, skilled behaviour in multilinguals — not a failure.

Types:
Inter-sentential: switching between sentences (‘Je suis fatigué. I need a break.’)
Intra-sentential: switching mid-sentence (‘She told me que j’avais tort.’)
Tag-switching: a tag or filler from L1 (‘It was fine, n’est-ce pas?’)

Code-switching shows metalinguistic competence — awareness of which system to use when.

What code-switching teaches us about learning:
1. L1 is a resource — not a crutch. Using your first language to reason through an L2 problem is efficient.
2. The most fluent multilinguals code-switch most freely — not least.
3. In the classroom: L1 use is a strategy, not a mistake to correct automatically.

Reflection questions

1. Is code-switching a sign of not knowing a language? No — research shows it’s a feature of high proficiency in both languages, not low proficiency in either.

2. What should a teacher do when a student uses L1 in class? Context matters: for clarification tasks, L1 may be appropriate. For output practice, encourage L2. Do not always ban L1.

3. What is ‘translanguaging’? A pedagogical approach that treats all of a learner’s languages as one resource — using them flexibly and strategically.

🧒 For younger learners: Ask children: ‘Which language do you dream in? Which do you count in? Which do you think in when you’re angry?’ Language identity is fascinating at any age.
👩‍🏫 Cambridge CELTA note: Code-switching awareness is a C1 topic valuable in multilingual classrooms and teacher training. Reference: CELTA topic area 1 (learners and their context) — consider learners’ linguistic backgrounds. Approach: normalise L1 for concept-checking; encourage L2 for fluency tasks.
