Overview / License

The purpose of the ESPDIC project is to create an electronic Esperanto-English dictionary in the form of a single Unicode (UTF8) text file with the following format :
"Esperanto : English" 
(i.e. Esperanto entry, space, colon, space, English definition - one entry per line). In some cases, a semicolon is used to show different definitions for Esperanto homonyms, e.g. "kajo : conjunction; quay, wharf". This simple formatting is designed to facilitate the integration of ESPDIC into other applications (which is highly encouraged).

History / Background

Based on the experiences I had with the CEDICT (Chinese-English Dictionary) project I started in the late 1990s, I decided to do something similar for Esperanto. The core of this dictionary was made up of vocabulary lists I created from various Esperanto textbooks as well as word lists I found on the Internet. The dictionary was then augmented by vocabulary lists I made from reading both print and online sources. In the early part of 2011 I believed that the dictionary had reached a sufficient size (about 30,000 entries) and I went through the dictionary from start to finish trying to catch the most obvious errors, formatting issues, etc. Any remaining errors or issues (and I'm sure there will always be some) are of course my own responsibility.

Current direction / volunteers

Now that the dictionary has reached over 60,000 entries, the focus of the project is primarily in two areas. The first is editing and correcting/proofreading the existing entries. Although ESPDIC has been essentially a one-person project for the first two years of its existence, I am actively looking for English-speaking Esperantists who would be willing to proofread/edit entries -- no level of participation is too small. The second area of activity will be translating and incorporating PIV (Plena Ilustrita Vortaro) entries that are not already in ESPDIC. My estimate is that there are approximately 20,000 PIV entries not currently in ESPDIC (although many, if not most, of them are proper names). This is also an area in which I am looking for volunteers.
