I bought the original edition of this dictionary when it was first published, and it has been a faithful companion since then. John Wells is a well respected champion of Esperanto, and an authority on pronunciation in all manner of languages, so you can rely 100% on his work. This new edition is as up-to-date as it's possible to be in a printed work. There is now a host of modern technological words, such as those connected with computers and the Internet. But that's not all! Given the more relaxed culture these days, Professor Wells has managed to include far more swear words than in the first edition. For anyone who doubts whether it's possible to be expressive in Esperanto, just give this book a try. It won't fail you, I promise. Well done, Prof. Wells, and equally well done Mondial for publishing such a treasure.
