Whenever you are confused about nesting levels, slowly walk through the process.

Our nestedArray has three large elements.

Here is `nestedArray[0]`

Here is `nestedArray[1]`

Here is `nestedArray[2]`

The word we are looking for is in `nestedArray[2]`

This array has two elements

Here is the first one `nestedArray[2][0]`

Here is the second one `nestedArray[2][1]`

The word we are looking for is in `nestedArray[2][1]`

Inside this array we have just one array.

Now we have `nestedArray[2][1][0]`

Then we have another array inside that

Now we have `nestedArray[2][1][0][0]`

If you just want to return the string `deepest-est? `

then we use bracket notation again to access the first element of that array.

Now we are at the final code of `nestedArray[2][1][0][0][0]`

Hope that helps!
