I think I've fixed this problem now...? I've also updated the description.

Very true. I think I've fixed this by using your first solution. Thanks again!

Thanks again! I didn't know how to make the random strings always include a space after punctuation so for simplicity's sake I was considering the punctuation as part of the 'word'. Is this confusing? Do you have any advice on how to improve this? This is my first attempt at authoring a kata so really appreciate your help.

There should have been a space either side of the dash - that should be fixed now. Thanks for spotting.
