Imagine you're talking with a French friend who's an expert baker. You've just tasted their croissant, and it's incredible. You want to know how they did it. In English, you might say, "You have to teach me!" or "Give me a lesson on this." In French, a common and natural way to say this is: "Fais-moi un cours dessus."

This informal phrase is your go-to when you want someone to explain something to you, whether it's baking, a video game, or a tricky concept from class. Let's break it down to see how it works.

The phrase is made of three simple parts:

1. Fais-moi: This combines two words. "Fais" is the command form of the verb faire, which means "to do" or "to make." "Moi" means "me." Together, "fais-moi" translates to "make me" or "do for me." It's an instruction.

2. Un cours: This simply means "a lesson" or "a class." It's the same word you'd use for a course at a university.

3. Dessus: This little word means "on it" or "about it." It's a handy preposition that refers back to the topic you were just discussing—in our example, the amazing croissant.

This expression is informal, so you'd use it with friends, family, or people you know well. It's perfect for situations where you're genuinely impressed or curious and want a quick, informal explanation.

For example, if your friend just beat a difficult level in a video game, you could say:

Wow, comment tu as fait ça ? Fais-moi un cours dessus ! (Wow, how did you do that? Give me a lesson on it!)

Or if a classmate quickly solves a complex math problem:

J'ai rien compris. Fais-moi un cours dessus, s'il te plaît. (I didn't understand anything. Give me a lesson on it, please.)

The key is that you're not asking for a formal, hour-long lecture. You're asking for a rundown, a set of tips, or a demonstration. It's a friendly way to ask someone to share their knowledge.

Now, let's check your understanding of this useful phrase.

And that's it! You've added another versatile, natural-sounding phrase to your French toolkit.
