1. Jeter l’argent par les fenêtres

Literal meaning: to throw the money through the windows

Actual meaning: This is one of the French idioms that originated in Medieval times when people used to give money to beggars by throwing it through the window. Although French people don’t do this anymore, the expression has been kept in the language and it now means that something is a waste of money.

Example: Je ne pense pas que ce soit le bon moment pour lancer ce produit. C’est comme jeter notre argent par la fenêtre. (I don’t think this is the right time to launch this product. I’m sure it will be a waste of money.)

2. Une bouchée de pain

Literal meaning: for a mouthful of bread.

Actual meaning: French bread is surely delicious, but it’s also quite cheap. Comparing something to a piece of bread means that it didn’t cost a lot of money.

Example: Je pense que nous devrions acheter ce nouveau logiciel. Regarde, nous pourrions l´avoir pour une bouchée de pain. (I think we should buy this new software. Look, it’s cheap as chips.)

3. Coûter les yeux de la tête/un bras

Literal meaning: to cost the eyes of one’s head, to cost an arm.

Actual meaning: No matter what language we speak, our eyes and arms are very dear to us. Saying that something costs your eyes or arms means that it costs a fortune.

Example: Nous n’avons pas assez d’argent pour une campagne marketing en ce moment. Cela nous coûterait les yeux de la tête. (We don’t have enough money for a marketing campaign right now. That would cost us an arm and a leg.)

4. S’en mettre plein les poches

Literal meaning: to put a lot in your pockets

Actual meaning: When you learn French (and French idioms!) you also get to learn about French culture. In France, having a lot of money is seen rather negatively because many people think that in order to get rich you need to exploit others. This idiom is used to criticise someone who makes more money than they need.

Example: Les patrons se mettent plein dans leurs poches grâce à notre travail acharné alors que nous pouvons à peine joindre les deux bouts. Qu’allons-nous faire à ce sujet? (The big suits are lining their pockets thanks to our hard work while we can barely make ends meet. What are we gonna do about it?)

5. Tomber dans le panneau

Literal meaning: to fall into the sign.

Actual meaning: Like most French idioms, this one also has an interesting origin. In the 15th century, the word panneau referred to the net hunters used to catch wild animals. In modern French, un panneau means “a sign”, but this expression means that you fell into a trap and that you only realised when it was too late.

Example: Allons-nous vraiment accepter la proposition du concurrent? On a l’impression de tomber dans le panneau ici! (Are we really going to accept the competitor’s proposal? It feels like we’re falling into a trap here!)

6.Faire le pont

Literal meaning: to make the bridge.

Actual meaning: If you don’t have to work next Friday, you might as well not work on Saturday either and enjoy a 3-day weekend, right? That’s what faire le pont means: to have a long weekend all to yourself (although, on second thoughts, you might want to use some of it to learn French!)

Example: Ce jeudi est férié, Je vais prendre un jour de congé et je fais le pont. (This Thursday is a holiday, I am going to take one day off and make the bridge.)

7. En prendre de la graine

Literal meaning: to take the seed from it.

Actual meaning: Seeds are what allow flowers to bloom, so if you take the seed from a person, it means that you steal their secret for success and follow their steps. (French idioms are rather poetic, aren’t they?)

Example: L’équipe de Sabine a obtenu d’excellents résultats, j’espère que vous prendrez la graine d’elle. (Sabine’s team has got great results, I hope you will follow her example.)
