Using idioms in French academic writing can make your work more interesting and help you express complicated ideas in a simple way. Here are some easy tips to keep in mind:

1. Know Your Audience

• Think about who will read your work. Some idioms might be too informal for serious academic writing, while others can help make your ideas easier to understand.

2. Choose Relevant Idioms

• Pick idioms that relate to your topic. For example, if you're writing about economic theories, you can use an idiom like "tirer son épingle du jeu" (to play one's cards right). This means making smart decisions in tricky situations.

3. Use Idioms Sparingly

• Don’t use too many idioms at once. If you overload your writing, it can become confusing. Use them wisely to support your main points.

4. Provide Context

• Sometimes, idioms need a little explanation. If an idiom might be unfamiliar to your readers, explain what it means. This is especially important in a diverse academic setting.

5. Practice Makes Perfect

• Read academic texts in French and pay attention to how idioms are used. The more you see them, the easier it will be to use them in your own writing.

By carefully using idioms, you can make your French writing better while still keeping it clear and professional.
