15 Essential French Idioms to Sound Native (CLB 9+ Usage Guide)

Total Word Count: 1,600+ words

In the TEF and TCF Canada exams, there is a massive gap between CLB 7 (Functional French) and CLB 9 (Advanced/Native-like). That gap is often defined by "Idiomatic Mastery".

Examiners are tired. They hear hundreds of candidates say "Je pense que c'est important" (I think it is important) or "Je suis très content" (I am very happy).

Imagine the impact when you look the examiner in the eye during Task B (Persuasion) and say: "Écoute, je ne veux pas tourner autour du pot, cette idée coûte les yeux de la tête !"

Suddenly, you are not a student reciting a textbook. You are a French speaker using cultural short-hands. This guide categorizes 15 powerful idioms by Exam Task and provides full dialogue examples.
