what is de, le, la, and les mean, when to use it. explain it like for a 5 years old

De, le, la, and les are all small words that we use in French to talk about things.

"De" is like saying "of" or "from" in English. For example, if we want to say "a piece of cake," we say "un morceau de gâteau" in French. It shows that the cake belongs to something.

"Le" is like saying "the" in English. We use it when we want to talk about something specific, like "the dog" or "the book." We say "le chien" for the dog and "le livre" for the book.

"La" is also like saying "the," but we use it when we're talking about a specific thing that is feminine. For example, we say "la fleur" for the flower, because "fleur" is a feminine word.

"Les" is again like saying "the," but we use it when we want to talk about more than one thing. So if we want to say "the dogs" or "the books," we say "les chiens" and "les livres."

Remember, it's important to use the right word depending on the situation. So, "de" when something belongs to something, "le" for something specific, "la" for something specific and feminine, and "les" when talking about more than one thing.
