Chiac is a special way of speaking that some people use in New Brunswick, Canada. It's like a mix of French and English words, and it sounds a little bit different from regular French and English.
Imagine you have two different superpowers, like being able to fly and being able to talk to animals. Chiac people have two different "superpowers" too – they can speak two languages, French and English!
Sometimes when Chiac people talk, they might say a French word and then an English word, or they might mix the two languages together. For example, instead of saying "Bonjour, comment ça va?" (which means "Hello, how are you?" in French), a Chiac person might say "Hello, comment ça va?"
Some people think that Chiac is really cool because it's a way to show that you can speak two languages at the same time. Others think that it's not a "proper" way to speak because it's not always easy to understand for people who only speak one language. But either way, it's awesome that Chiac people have the ability to use two different languages and express themselves in unique and interesting ways!
