I notice a reference to the "translation" of Harry Potter in the World Wide Words site that you mention, Mav.

One night I received a late night (for me) message from AnnaStrophic. She had got to the part where Harry And Hagrid were sitting by the fireside. I had mentioned in a post around that time that I had never seen an "English muffin" until I went to the USA, yet here was Harry eating English muffins! She asked me to check out my UK edition. I raced upstairs, crept past sleeping children to find the book by my daughter's bedside. I found the page in question and there was Harry Potter, sitting with Hagrid, eating ... crumpets. English muffins really doesn't give anything like the same upelevating image!
