Declan's Chinese Dictionary uses the 20,000 word CEDICT Chinese-English dictionary database. Both the GB (Simplified) and Big5 (Traditional) versions of the databases can be used. Declan's Chinese Dictionary allows flexible searches of the dictionary including Pinyin searches (with and without tone numbers). The program also features a character reference database which displays radical information, stroke count and more for each individual character selected. The program includes a feature that allows custom word lists to be exported to Declan's Chinese FlashCards XFL files. Full integration with the windows clipboard is also included which allows the word, its pronunciation or its meaning to be pasted into other Windows applications.
