I dont understand

I do not understand why we call the function greeting, then have the tuple named greeting along with the constant

tuples.swift 
func greeting(person: String) -> (greeting: String, language: String) {
    let language = "English"
    let greeting = "Hello \(person)"

    return (greeting, language)
}

The best answer I can come up with is, it was done to confuse you and make the challenge a bit more difficult. It seems a lot of people get stuck on the fact greeting is used various time.

Actually, I guess it's fairly likely greeting and language was used in multiple places to get us to realize that though three different elements have the name "greeting", they're not connected to each other. Function names, tuple parameters (or whatever they're called), and function properties are their own entities.
