Hi there,

I think if you remove from the letters iterable, you will start skipping elements in your for loop. If you are at element 2 and you then remove it, what was element 3 becomes element 2; so your next loop iteration will skip the original 3 and go straight to 4 (which is now at 3!). I hope that made sense!

To complete this, I created an output string and initialized it to be empty at the start of the method. I then created a list of lowercase vowels.

I looped over word. If each element (lowercased using lower()) was not in the list of vowels, I added it to the output string. At the end of the loop, I returned the output string.

I hope that helps - shout if you need more.

Steve.
