You declare a constant typing 'let' and then the name of the constant. The task asks you to name the constant language, so that is it's name. Then, you you say what the constant is, or what the constant is equal to, or what the constant is holding.. So, if you want your constant to be a string like "Swift", you set the constant equal to " Swift". the quotes mean it's a string, so that's why you use them.

It might look like this:

let language = "Swift"
