You’re mid-sentence. You can see the idea clearly. And then the exact word you need in your target language disappears, like it was never yours.
So you do what your brain is designed to do under pressure: you borrow. A word from English. A phrase from your home language. A half-remembered connector from last week’s vocab list. And now you’re wondering if IB Languages actually allows this, or if you’ve just sabotaged your grade.
When your brain opens three dictionaries at once.
The quick answer for IB Languages: yes, but be strategic
In IB Languages, mixing languages (often called code-switching) is normal in real life. In exam life, it depends on the task.
Use this simple rule:
Speaking: a tiny amount of code-switching can keep you moving, but too much reduces the evidence of your language ability.
Writing: avoid it unless the task is explicitly multilingual (rare). In most IB Languages writing tasks, mixed language usually reads like an error, not a strategy.

A practical checklist: what to do the moment you’re stuck
When you freeze, your goal is not “perfect vocabulary.” Your goal is “keep producing clear meaning.” Try this ladder, in order:
Rephrase using simpler words you already know.
Use a synonym (even if it’s less precise).
Shorten the sentence and rebuild.
Use a safe connector (however, because, therefore) and pivot.
Only then, use a quick code-switch as a temporary bridge.
This is exactly how high scorers treat pressure: not as a crisis, but as a decision tree.
No code-switching required!
When mixing languages helps (and when it quietly harms)
When it helps IB Languages performance
Code-switching can help you in IB Languages when it does one of these:
Preserves fluency: you keep your rhythm, which matters in speaking assessments.
Protects your idea: you don’t abandon a strong point just because one noun is missing.
Buys time: you use one borrowed word while you quickly return to the target language.
A good example is during oral practice: you drop one word, then immediately repair the sentence.
When it harms IB Languages performance
It starts to hurt when it becomes a habit:
It signals dependency: the examiner hears you reaching for the “easy exit.”
It disrupts accuracy: grammar and syntax drift when you keep switching.
It reduces evidence: in IB Languages, marks come from what you demonstrate, not what you meant.
Is mixing languages allowed in IB Languages exams?
In IB Languages, the exam and assessment tasks are designed to measure your ability in the target language, so the safest assumption is that you should stay in that language as much as possible. In speaking contexts, a brief slip or borrowed word can happen, and examiners generally recognize that real communication is imperfect. The key is what you do next: if you immediately repair and continue fluently, it looks like normal communication pressure rather than a lack of control. In writing tasks, mixing languages is much riskier because it sits on the page as an accuracy issue and can interrupt clarity. If you’re unsure, train a “rephrase first” habit so you almost never need to switch. That habit is a scoring advantage in IB Languages, not just a coping mechanism.
Will code-switching lower my marks in IB Languages speaking?
It can, but not automatically. In IB Languages speaking, assessors look for clear communication, range, and accuracy, and frequent switching reduces the evidence you’re providing in the target language. One borrowed word is usually less damaging than a long pause that breaks your fluency and forces you to abandon your point. The bigger risk is repeated reliance: if every complex idea triggers a switch, your performance starts to sound less controlled. A practical fix is to learn repair phrases and “safe paraphrase routes” for your common themes (identities, experiences, social organization, etc.). Record yourself practicing and count how often you switch--then turn those moments into Flashcards. Over a few weeks, you’ll notice that IB Languages fluency improves because your brain trusts you to recover.
What should I do instead of mixing languages when I’m stuck?
Start by shrinking the sentence. In IB Languages, a correct simple sentence usually scores better than a broken complex one. Then paraphrase using words you already own, even if they are less precise--precision grows later, but control matters now. Next, use connectors to protect structure: “however,” “because,” “as a result,” “for example.” If you still need help, ask a clarification question (in the target language) or pivot to an example you can describe confidently. Finally, if you’re practicing at home, use the moment as data: write down the missing word or structure and drill it with spaced repetition. On RevisionDojo, this becomes easy because you can review with Study Notes, drill with Flashcards, and practice with the Questionbank while using AI Chat to generate alternative phrasings.
The bottom line: IB Languages rewards recovery, not perfection
Mixing languages when you’re stuck isn’t a moral failure. It’s a signal: your brain wants to keep the meaning alive.
In IB Languages, the smarter move is to treat code-switching like a temporary bridge, not a home. Train repair phrases, paraphrase routes, and short sentence rebuilds so you can stay in the target language under stress.
