Keep up-to-date!  Completely revised and rewritten, with a thorough coverage of  both contemporary English and Esperanto. 

Check how to write and speak Esperanto via the clear and authoritative introductory grammar.

The format and style of the dictionary remain unchanged from the first edition – it is still compact.  It assumes that users have enough knowledge of both languages to work out for themselves most derived and inflected forms of words, given the base forms.  Entries are as far as possible one-word equivalents.  Polysemy is treated very summarily, and the number of prefixed, suffixed, and compound words recorded is quite limited.

There are some 10,150 Esperanto roots (headwords) in this dictionary, as against the inflated 16,780 (many of them virtually never used in practice) to be found in PIV.  Many are specialist terms of various kinds.  For everyday purposes the user of Esperanto needs no more than three or four thousand roots.  The dictionary does however include some 150 roots not included in PIV.  Virtually all of these can be found in use in Vikipedio or other documents on the internet
