Register Mastery: Soutenu vs Courant vs Familier
Total Word Count: 1,800+ words
French is a class-conscious language. You use different vocabulary and grammar depending on who you are talking to. The difference isn't just politeness; it's a completely different dictionary.
TEF/TCF tests this explicitly:
- Reading Section A: Identifying the nature of a text (Friend letter vs Admin letter).
- Speaking Task A vs B: Switching registers instantly.
- Listening Section D: Recognizing slang.
There are 3 main registers: Soutenu (Formal), Courant (Standard), Familier (Slang/Informal).
Level 1: Familier (Slang / Informal)
Context: Friends, Family, Teens, Text messages. Grammar: "Tu", dropping "Ne" in negation, Contractions, Slang words.
- "J'sais pas." (Instead of Je ne sais pas).
- "T'es là ?" (Tu es là ?).
- "C'est ouf." (C'est fou).
Level 2: Courant (Standard / Neutral)
Context: Work, Everyday transactions, Strangers, News. Grammar: Standard grammar. "Est-ce que...?", standard negation.
- "Je ne sais pas."
- "Tu es là ?" / "Vous êtes là ?"
- "C'est incroyable."
Level 3: Soutenu (Formal / Literary)
Context: Job interview, Letter to Mayor, Literature, Official speeches. Grammar: Inversion of subject ("Que voulez-vous ?"), Sophisticated synonyms, "Nous" instead of "On".
- "J'ignore la réponse." (Instead of Je ne sais pas).
- "Êtes-vous présent ?"
- "Cela est stupéfiant."

Reading Section A: If the text says "Salut mec", the answer is "Lettre amicale". If the text says "Monsieur le Directeur", the answer is "Lettre formelle" or "Administrative".
Speaking Task A:
Conclusion
Passing C1 means Control. A native speaker knows "La bagnole" but never uses it in a job interview. An advanced learner often uses "Voiture" everywhere. To sound native, you must know when to say "C'est ouf" and when to say "C'est remarquable."
