"During the twentieth century, both English and Esperanto have developed--most strikingly in the large number of scientific and technical words which have penetrated from purely specialist vocabularies into that of the layman. These developments have resulted in an increasing need for a new comprehensive and yet concise two-way Esperanto and English dictionary. This compilation has been designed to satisfy these requirements. It caters for beginners, ordinary users and advanced students alike, utilising to the full the regularity with which, in Esperanto, parts of speech, derivatives and compounds are formed from a single root. This simplicity also means that, whereas the English-Esperanto section comprises about 19,500 entries, these can be condensed to 9,000 in the Esperanto-English section. Accuracy has been ensured and anglicisms avoided by making use of a wide range of international reference works. This dictionary will be of value to all who look to Esperanto as the practical solution to the world language problem."--Jacket.
