You can know French grammar, memorize hundreds of vocabulary words, and still feel lost when native speakers start talking.
Why?
Because real French is not always the French you learn in textbooks.
French speakers use everyday expressions, slang words, and even verlan (a word game where syllables are reversed) to sound more natural and relaxed.
In this guide, discover 10 French slang words that will help you understand conversations and sound more like a native speaker.

Do not use it in formal situations like job interviews.
