What exactly are Tuples? Is the combination of two strings within () a tuple?

I thought that I was doing this right but I keep getting an error. I don't understand why this is happening.

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

    return greeting
}

In Apple's Swift documentation, tuples are described as a list of zero or more elements, separated by commas, enclosed in parentheses.

For the purpose of function return values we're going to assume a tuple is a list of two or more items, separated by commas, surrounded by parentheses.

The task instructions tell you to change the return value into a tuple. Your guess in the title is very close to the right answer! Can you figure it out now?
