CEFR C1-C2 · 5 min
Bengali at home. English at work. French with neighbours. Hindi when I dream. I didn’t plan to become multilingual — it happened because I moved, because I had to, because language follows necessity. What I discovered is that each new language does not replace the others. They stack. They interfere. They also teach you things about each other that monolingual speakers never see. This lesson is about what happens inside a multilingual mind — and what it reveals about English.
Today's focus: Code-switching, interference errors, and what multilingualism reveals about English structure
Code-switching is the natural alternation between languages in a multilingual speaker. It is sophisticated — not lazy or confused.
Interference errors happen when an L1 pattern enters L2. They come from your strengths, not your weaknesses:
- French → English: ‘I have 25 years’ (j’ai 25 ans → I am 25). Article omission (‘Go to hospital’ vs ‘Go to the hospital’)
- Bengali/Hindi → English: ‘She is more tall’ (no comparative morphology). ‘Is it?’ as universal question tag.
- All → English: Overuse of present continuous (‘I am liking this’ → stative verbs don’t use continuous)
Recognising your interference errors is the fastest path to eliminating them.
Examples in context

▶ Correct this: ‘I am knowing the answer.’ Why is it wrong?
Other stative verbs: believe, understand, want, need, love, hate, see, hear. These describe states, not actions in progress.
▶ What language likely caused this error: ‘She asked me that I come early’?
Identifying your L1 as the source helps you target the specific rule to correct. It’s efficient, not embarrassing.
▶ Is code-switching a sign of poor language ability?
Grosjean (1982) and many others have shown that bilinguals are not two monolinguals in one — they are a unique language system. Code-switching is evidence of competence, not confusion.
Your interference errors come from your strengths — they prove you have a strong L1. Identify them, name their source, fix them. Multilingualism is not a limitation — it is a lens that shows you what English actually does.
