Franglais is like when you mix two different languages, French and English, together to make a new type of language. It's kind of like when you play with blocks and mix the colors together to make different shapes and patterns. In Franglais, you might use words that are from both French and English, like "le weekend" instead of "the weekend" or "un sandwich" instead of "a sandwich". Sometimes the meaning of these words can be different, so it's important to be careful when using Franglais so that people understand what you're trying to say. It's a fun way to play with language and talk with different people from different countries who might speak different languages!
