Hey Zachary Dunn,

You are a little bit off on your concatenation, but don't worry, because I will help ya! First off, when we concatenate two or more arrays, we just use that "concat" method. There's no need for any + sign as this only applies to strings or string variables.

So, the first part of Task 1 should look like:

var saying = first.concat(second);

But, we're not done yet, because the challenge wants us to add the word "dog" to the concatenation of the arrays. Well, that's no problem, because all you have to do to add in more strings/arrays, is to add a comma between whatever we want to add. So, since we want to add "dog" to the end, all we gotta do is:

var saying = first.concat(second, "dog");

The saying variable will now look like: ["The", "quick", "brown", "fox", "jumps", "over", "the", "lazy", "dog"]. Does that make sense?
