The CEDICT project was started by Paul Denisowski in 1997 and is maintained by a team on mdbg.net (a website registered for the purpose by Dutchman Dennis Vierkant) under the name CC-CEDICT, with the aim to provide a complete Chinese to English dictionary with pronunciation in pinyin for the Chinese characters.
CEDICT is a text file; other programs (or simply Notepad or egrep or equivalent) are needed to search and display it. This project is considered a standard Chinese-English reference on the Internet and is used by several other Chinese-English projects. The Unihan Database uses CEDICT data for most of its information about character compounds, but this is auxiliary and is explicitly not a part of the main Unicode database .
- Traditional Chinese and Simplified Chinese
- Pinyin (several pronunciations)
- American English (several)
- As of 14 February 2016[update], it had 114,087 entries  in UTF-8.
The basic format of a CEDICT entry is:
Traditional Simplified [pin1 yin1] /American English equivalent 1/equivalent 2/ 漢字 汉字 [han4 zi4] /Chinese character/CL:個|个/
Example of a simple egrep search:
$ egrep -i 有勇無謀 cedict.txt 有勇無謀 有勇无谋 [you3 yong3 wu2 mou2] /bold but not very astute/
